1) A sample of gas has a mass of 38.8mg . Its volume is 224 mL at a temperature of 54C and a pressure of 906torr.
Find the molar mass of the gas.
2) A gas mixture contains each of the following gases at the indicated partial pressures: N2, 320torr; O2, 124torr; and He, 212torr.
What is the total pressure of the mixture? (in torr)
3)A 1.25 -g sample of dry ice is added to a 760 -mL flask containing nitrogen gas at a temperature of 25.0C and a pressure of 725mmHg. The dry ice is allowed to sublime (convert from solid to gas) and the mixture is allowed to return to 25.0C
