Ideal Gas Law

Molar Mass of a Gas


<div class="wp-block-create-block-problemblock">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?</div>
