The molar mass of a volatile liquid(one which vaporizes easily) can be determined by a the 'Dumas Method.' In this process a small amount of the liquid (a few drops) is placed in a clean flask. The mouth of the flask is civered with a piece of foil that has a small hole (pin hole) in it. The flask is heated in a boiling water bath until the liquid vaporizes completedly.
