The following procedure is a simple though somewhat crude

wayto measure the molar mass of a gas. A liquid of mass 0.0184 g

isintroduced into a syringe by injection through a rubber tip using

ahypodermic needle. The syringe is then transferred to a

temperaturebath heated to 45 degrees C and the liquid vaporizes.

The finalvolume of the vapor (measured by the outward movement of

theplunger) is 5.58 mL and the atmospheric pressure is 760 mmHg.

Giventhat the compound's empirical formula is CH2, determine the

molar mass of thecompound.
