- A solution of 5.00 g acetic acid in 100 g benzene freezes at 3.380C. A solution of 5.00 g acetic acid in 100 g water freezes at -1.490C. Find the molecular weight of acetic acid from each of these data. What can you conclude about the state of the acetic acid molecules dissolved in each of these solvents?A 10.00 mL sample of ethanol is added to 250.0 mL of water in order to observe the freezing point depression of the water. Consider the possible errors in this experiment, and determine whether each would cause the freezing point of the water to increase, decrease, or remain the same compared with the expected results. It is discovered that the 10.00 g ethanol sample is actually 95% ethanol and 5% water. The ethanol sample is left out for several minutes before being added to the water, allowing a significant amount to evaporate. Instead of starting the experiment with room temperature water, the experiment is started with cold water. Some of the water is splashed out of the container before the ethanol is added. Some of the ethanol and water solution is spilled out of the container during temperature measurement.Suppose you are recrystallizing a compound and boil the solution for so long that a substantial amount of liquid evaporates. What is likely to happen to some of the solute? What should you do if this occurs?
