3. Results and Discussion 3.1 Excess molar volume The experimental values of densities for pure components and their binary mixtures as a function of mole fraction at T = (303.15 to 313.15) K are given in Table 2. Excess molar volumes V^E were calculated from the measured values of density using the following equation: 〖 V〗^E = V_m-V_1 x_1-V_2 x_2 (1) V^E=((x_1 M_1+x_2 M_2)/ρ_m

Volume Lab In this four parted lab the purpose is to use measurement and water displacement and calculations to find the volume of various objects. Part A questions were how much drops of water were needed to make 1mL the original hypothesis made was ten drops however this was proven wrong once the data in which twenty drops of water rose 10 mL of water to 11 mL of water, nineteen to rise from 11 mL to 12 ml, and finally eleven drops of water to rise from twelve mL to thirteen mL. Once the average

INTRODUCTION Density, mass divided by volume, is one of the most important characteristic of matter (Sciencing) since it affects whether objects will float or sink, thus making it hugely important for the workings of the universe and in daily live (Sciencing). All objects have density and that density can increase or decrease as the result of actions taken on the object (Sciencing), such as adding salt into a substance like water, as has been done in this particular experiment. When salt is dissolved

Spiritual Truths about Surface Area and Volume All objects have a certain amount of volume. They also have their own surface area. These two geometric terms have their own unique formulas. The formula for the volume has special formulas for different objects. The equation for volume of cylindrical figures is V=A(B)*H; of conic figures is V= ⅓ A(B)*H; of spheres is (4/3)()(r3). The formula for the surface area has various equations for different objects. The equations for surface area of objects

Graphing to Determine the Density of Unknown Metals Purpose: The purpose of this lab was to graph and compare measurements of mass, volume, and density of two unknown metals. Relationships in data and physical appearances were observed and used to identify each metal. The density was shown as the slope of the graph as both were equivalent to mass divided by volume. The experimental density was then compared to the actual value and a percent error was determined. Materials: Equipment and materials

results tested in the lab. One significant finding of the experiment based on the data about the three cubes was the inverse relationship which was as cell size increases, the surface area to volume ratio decreases. To find the ratios, the calculation of the surface area of each cube (length x width= cm^2) and the volume of each cube (length x width x height= cm^3) was necessary. As a result, the ratio of surface area to

“P1V1 = P2V2” shows that as the volume increases, the pressure of the gas decreases in proportion, as long as the temperature stays the same. The relationship between pressure and volume was first noticed by mathematician and astronomer Richard Towneley and experimenter Henry Power. Robert Boyle, a chemist and physicist, confirmed the discovery and published the results in 1662. According to science historians, Boyle’s assistant, Robert Hooke, built the experimental rig. The law is based on air

mentions the Column volumes of Gel Filtration experiment: Void Volume (Vo), Elution Volume (Ve), Included Volume (Vi), Entire Volume (Vo + Vi), and Inert Volume (Vg). Void Volume (Vo) came out to be 1.25 ml. It was calculated by adding all the fractions that contained blue dextran. Blue Dextran was the biggest substance in size which made it impossible to fit in the available pore sizes of the beads. Void Volume represents the space between the beads in column. In addition, Elution Volume (Ve) came out

Density: A Characteristic Property I Purpose The purpose of this experiment is the density of six different substances. The way to figure this out is by finding the mass and volume of each of the substances. The hypothesis for the different experiments is that with each of the different substances and mixtures will be different depending on what they are. II Equipment The late nite lab was used to conduct this experiment. The product used were a balance, a graduated cylinder, water, Ethanol, and

The first measurement that was retrieved as the mass of the metal object was 24.15 g. This was repeated for a second measurement of 23.85 g, and a final measurement of 23.82 g. All three mass measurements were recorded. Moving forward, to find the volume of the metal object, the graduated cylinder

since our standard deviations are zero, this means our pipetting was accurate. The accuracy can also be determined by comparing the expected mass with the mean mass that gained in practical. For the volume of 738.5 μL (0.7385ml), since the density should be one, by deriving the formula of density = mass/volume, the expected mass is 0.7385g. By comparing the expected mass (0.7385g) with the mean mass (0.7100) that gained from the practical, the difference of the values is small (0.0285g), so

metal on a scale, then using water displacement, finding the volume of the metal. First, we decided to use metal B. We took out one piece of the metal and measured the mass by placing it on the scale. Then, we filled up the graduated cylinder with exactly 20 mL of water. After filling up the cylinder, we gently placed the metal inside and recorded the new volume of the water. Each time it was the same, 24.0mL. We then realized that the volume of metal B itself was 4.0mL. After doing the same process

physical property of matter, as each element and compound has a unique density connected with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For gases the density may amount with the number of gas molecules in a constant volume. Helium balloon: Compare the behavior of helium filled balloon with that of an air filled balloon. Even taking into account the weight of the rubber balloon, the helium balloon floats on the air and is

In the experiment for “ If the Earth has layers , then the most dense material will be located towards the center.” the hypothesis was accepted. The data used from the experiment that supports the hypothesis was that the floating film canister density was 0.47 g/mL3 and it was the least dense out of the three. The floating film canister represented the crust of the Earth. The suspended film canister represented the mantle and it had a density of 0.80 g/mL3. The sunk film canister was representing

Osmosis Lab Report Research Question: How does the change in the concentration of a sucrose solution affect the process of osmosis in a potato cell by measuring its mass? Background information: 1 Osmosis is the process by which a liquid passes through a semi-permeable membrane, moving from an area with a high concentration of water to a low concentration of water. There are various factors that affect osmosis such as: concentration, surface area and temperature. The concentration of solutions

delivery rate needed is 750 GPM or 625 IGPM. A total of 1300 ft. of 4 inch high volume (13 lengths of 100 ft. hose) will be needed from the hydrant to the Clubhouse. To determine how many pumpers will be sufficient to supply the water, we need to find out the friction loss (FL) for each 100 ft. of high volume hose. Here’s a few technicalities I found in my readings. The operating pressure of a 4 inch high volume should not exceed 185 psi. The intake pressure should be “ideally maintained at

able to package products properly if engineers know exactly how fast the item flows out of the machinery. Solids, liquids and gases are the commonly known states of matter that consist of distinguishable physical properties. A solid has a fixed volume and shape consisting of rigid particles locked into place. Because a solid’s particles have little free space to slide past one another, solids are not easily compressible and do not flow easily. An example of a solid is a couch. A

Matthew Brayton Physics Measuring Lab Report: Purpose: To practice measuring, calculating uncertainty, and creating data tables. In this lab we measured 5 things - The surface area of the top of the one table, the volume of the room in square meters, the width of a single piece of paper, the length of my foot, and the circumference of my head. Data Table for the surface area of the top of one table: Length l /cm +/- 0.4cm Average Length (LAvg) / cm +- 0.4 cm Width (w) /cm +/- .3 cm Average

the differences in density between soft drinks. Rather than calculating using two different methods to calculate for the same substance we had two different soft drinks, diet and non-diet Coca-Cola. We then used two volumetric pipets to measure the volumes of the soft drink, then placed the soda in a beaker to calculate the mass using an analytical balance. The questions that I considered before beginning the experiment were, “How does each method of calculating density affect the outcome?’ “How does

13. Birds Nest Aquifer 3D Model - Bottom view. (National Council of Teachers of Mathematics, n.d.) Created using an isometric drawing tool. (not to scale) METHOD The formula used to get the aquifer is the same general formula used to get the volume for pools and ponds. The result will be given in gallons and will then be converted in barrels. The total capacity will be multiplied by the porosity to get an idea of the Birds Nest aquifer’s capacity in barrels of produced water. The steps to do
