An organic chemist isolates a colorless liquid from a petroleum sample. She places the liquid in a pre-weighed 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: Volume (V) of flask = 196 ml T = 99.1°C P= 751 mmHg mass of flask + gas = 81.5 g mass of flask = 78.3 g Calculate the molar mass (in g/mol) of the liquid.

Question
An organic chemist isolates a colorless liquid from a petroleum sample. She places the liquid in a pre-weighed 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:
Volume (V) of flask = 196 ml T = 99.1°C P= 751 mmHg
mass of flask + gas = 81.5 g mass of flask = 78.3 g
Calculate the molar mass (in g/mol) of the liquid.
