What Are The Unique Properties Of Ring 1 And Ring Two Molecules
Which was 117.60 grams for substance 1, 87.71 grams for substance 2, 54.7 grams for substance 3, 25.11 grams for substance 4. Once we finished weighing each unknown substance we started figuring out the g/mol mass of each compound that the substances could possibly be, which is how we got to Table #2 above. In order to find the g/mol mass of each of the compounds, we had to find the molar mass of each element, then multiply and add accordingly. I'll use K2SO4 as an example of how to calculate the molar mass of a compound. The elements in K2SO4 are Potassium, Sulfur, and Oxygen.
To calculate the experimental mass the substance of each bag and the bag its self was measured using a balance. After gathering the mass subtract the mass of the empty bag to the mass of the unknown substance, in order to just have the mass of the substance. Afterward the mass of the unknown substance was divided by the number of moles recorded on the bag of the substance. The measurements are displayed on the table
The Controlled Variable for this experiment was mass and volume. When identifying an unidentified object finding the density is the easiest way to do it because, any pure substance has a specific density at a specific temperature and each element and compound has a unique density associated
In this week’s lab we had to determine the density of a quarter, penny, and dime. My question was “How does is each coin?” Density is the amount of mass in an object. To find the density of each coin in this lab, we used a triple beam balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis.
The purpose of this experiment was to observe the relationship between different solutions and their effect on the mass and length of a gummy bear. Gummy bears with the same relative size and colour were placed in 50 mL beakers with the same amount of their designated liquid. The different solutions studied were water, oil, vinegar, a simple sugar solution, and rubbing alcohol. In the end, based on the observations made, the majority of the hypotheses created were not proven to be correct.
2. Which physical properties did you examine in this activity? The physical properties that we examined in this activity were state, colour, texture, clarity, shape, and hardness. We did this by examining each powder with a magnifying class once we placed it on the watch glass.
Wt. Mass Density Appearance 2-methycyclohexanol 0.75 mL 114.19 g/mol 0.93 g/mL Clear colorless liquid 85% Phosphoric acid 1.00 mL Clear
The interesting two mystery materials have some differences but have many similar details too.
Introduction This report discusses an experiment to study the correlation using the molar mass of elements to identify unknown substances by weighing the mass of the substance and calculating the grams per mole. The main objective of this experiment is to determine the mass similarities between the given and unknown substances. The equation used in this experiment is: Molar Mass = Mass (g) / Mol Where the molar mass of the unknown substance, the mass of the unknown substance, Mol is the number of moles in the unknown substance. These results will be compared to the molar mass of the given compound.
Did the Constitution Establish A Just Government? In July of 1776, soon after the Declaration of Independence was signed, The Second Continental Congress was faced with the arduous task of creating a piece of legislation that would help govern their nation successfully. They drew concepts from the Enlightenment including, but not limited to, the idea that the governments main goal was to protect the natural rights of citizens and that the government received all its power through a social contract. These ideas enabled them to draft the Constitution of 1787, which is the basis of modern American government.
Molecular Structure Lab Report: Determining Polarity Instructions: For this investigative phenomenon, you will investigate why certain substances, such as oil and vinegar, don't mix. To do so, you will combine various compounds, compare their solubility, and determine their polarity. Fill in each section of this lab report and submit it to your instructor for grading.
In the lab “All That Glitters” the objective that was focused on during the lab was calculating the density, volume and mass of various substances. The method that was used in finding the volume of the samples is called the displacement method. This is a process where the volume of the water in the graduated cylinder is calculated before and after the sample is placed. In this lab, the goal of the experiment was to identify and come to consensus about what the unknown substance might be. For this experiment, the required materials were ten pre and post pennies, unknown sample, graduated cylinder, weigh boat, water, paper towels and a weighing scale.
One example of these similarities and differences between Arcite
Eric Hou Ella Lichey, Jenna Poulton, Landen Lee Honors Biology Block 4 February 13, 2023 The Effect of Type of Oreo Cookie on the Mass of the Filling Purpose This lab aimed to determine if Double-Stuff Oreo cookies were really “double the stuff” of a regular Oreo cookie. In this lab, we compared the mass of the filling for both Oreos to determine if the mass of the Double-Stuff Oreo’s filling was twice that of the regular Oreo’s filling.
I. Purpose: To experimentally determine the mass and the mole content of a measured sample. II. Materials: The materials used in this experiment a 50-mL beaker, 12 samples, a balance and paper towels. III.
