2) Given the data on the next page on the ethanol-water system, determine the following: a) Make a plot of the molar volume of the solution vs. mole fraction of ethanol.
b) On the same plot, graph the molar volume of the solution as a function of mole fraction ethanol if the volumes of pure water and pure ethanol could simply be added.
c) Determine the partial molar volume of both ethanol and water for a solution made from 50 mL of ethanol and 20 mL of water.
d) Using those partial molar volumes, confirm that the total molar volume of a solution of 50 mL ethanol and 20 mL water is not 70 mL.
