Organic Chemistry Answers

an organic chemist isolates a colorless liquid from a petroleum sample she places the liquid in preweighed flask and put the flask in boiling water which vaporizes the liquid and fill the flask with gass she closes the flask and reweighs it she obtained the following data
volume of flask =213ml
T=100.0 degree celcius , p= 754
mass of flask+gass=78.834g
mass of flask = 77.83 g
calculate molar mass of liquid
