She places the liquid in a preweighed flask and puts the flask in boiling water, which vaporizes the liquid and fills the flask with gas. She closes the flask and reweighs it. She obtains the following data: V=213 mL T=100°C P=754 torr Mass of flask + gas= 78.416 g Mass of flask= 77.834 g Calculate the molar mass of the liquid.
