The following procedure provides a crude method of determining the molar mass of a volatile liquid. A liquid of mass 0.0153 g is introduced into a syringe and the end is capped (sealed). The syringe is transferred to a temperature bath maintained at 58.5 oC, and the liquid vaporizes. As the liquid vaporizes the plunger is pushed out. At equilibrium, the plunger reads 5.76 mL of gas. Atmospheric pressure is 740. mmHg. What is the approximate molar mass of the compound (in g/mol)?
