Introduction A way to determine the molar mass of an unknown substance is to use other properties of that substance and solve for desired information. In this experiment, a colligative property, like the freezing point of an aqueous solution of the unknown substance, was used to find the molar mass of the substance. With the molar mass discovered, the identity of the substance was found. Material and Methods First, a Vernier temperature probe was attached to a plastic rod using rubber bands.

Purpose: The purpose of this experiment was to determine the molar mass of unknown #43 using the derived freezing point depression. To obtain the freezing point depression, t-butyl alcohol was placed in a cold-water bath and frozen solid for a total of two runs. Then, unknown #43 was dissolved in t-butyl alcohol and placed in a cold-water bath until frozen solid. This process was repeated for a total of three runs, with the first two runs containing half of the unknown, and the last run containing the full amount of unknown.

Synopsis This laboratory report gives an outline of the experiment which was carried out in order to measure the density of water at different temperatures via two different methods. The lab consisted of two parts. In the first part the density of water was measured by hydrometer. At first the density of water at room temperature was measured.

The documentary "Trouble the Water" is filled with stories and different accounts of the aftermath of hurricane Katrina. The film begins by introducing Kimberly Roberts and her husband. They are the main characters of this film. The first part of the film shows the day leading up to the hurricane as shot by Mrs. Roberts home video. It focuses on the evacuation order and the people who are not able to leave for lack of transportation.

The goal of this lab was to find the molar mass of an unknown volatile liquid using the provided equipment and knowledge of gases. In order for this to be accomplished, many variables needed to be measured, like the pressure of the room, the molar mass of the gas, the volume of the gas, and the temperature of the water the gas was in. First, the volatile liquid was heated up until it evaporated. After collecting the required data, calculations were done to determine the molar mass of the compound. Key terms used in this lab are the ideal gas law, PV = nRT, which was used in finding the molar mass.

Today’s experiment was conducted to determine the molecular weight of an unknown fatty acid based on the freezing point depression. In order to do this we needed to heat about 9 grams of Stearic acid to a temperature of 85 degrees C, through the means of a water bath. After heating the stearic acid, we remove it from the hot water bath and stirred it until the temperature did not fluctuate more than .1 degrees for 4 readings. This allowed us to determine the freezing point for pure stearic acid. Next we added about 1 gram of an unknown fatty acid and repeated the same steps as above.

Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.

Introduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4

The mixture was then distilled. When the temperature was reached to about 59℃, half vial of distillate (1V) and 1 mL of the liquid residue (1L) were collected. For 61.0℃, the distillation was then continued. Samples (2V, 2L) were taken at about 61.0℃.

There are multiple points both at 43°C and at 72°C which indicates that liquid was collected at these temperatures. Based on this information, it would appear that two different liquids were present in solution and that one liquid has a boiling point of approximately 43°C and that the other has a boiling point of approximately 72°C. The literature value boiling point for DCM in is reported to be about 40°C and it is about 80°C for cyclohexane. Based on the graph, DCM was collected from 4 ml to 22 ml, thus 18 ml of DCM was collected.
