you determine that the mass of a Florence flask and a piece of aluminum foil weigh 39.964 g. After performing the experiment on an unknown, you find that the flask, foil, and condensed vapors weigh 40.312 g. The flask was removed at 91.7oC when all the liquid was vaporized. At the end of the experiment you place the Florence flask and foil on the balance, fill the flask with water at 20.2∘ C, and find a mass of 163.638 g. If the current barometric pressure is 758 torr, what is the molar mass of your unknown?
