(MM) of a volatile liquid using th ideal gas law (PV=nRT) in the following form:

MM=(mass of vapor * R* boiling point in Kelvins) (Pressure in Atmospheres * flask volume). If R=0.0821 liter-atmospheres/mole-degree K, the flask volume is 275 ml, the pressure is 775 torr., calculate the following:

1. The density of the vapor for CH2Cl2 at 70 degree C

2. The experimental molar mass of CCl4 if the mass of vapor in the flask is 1.44 grams at 90 degree C
