Molar Mass of a Gas

Home | General Chemistry 1 | Ideal Gas Law | Molar Mass of a Gas

The label on a cylinder of a noble gas became illegible, so a student allowed some of the gas to flow into a gas bulb with a volume of 0.3000 L until the pressure was 0.901 atm. The sample then weighed 1.45 g and its temperature was 27.0 ^{\circ}C. What is the molar mass of the gas? Which noble gas is it?
