We’re being asked to identify the unknown gas given the rate of effusion of O2.


Recall that Graham's Law of Effusion allows us to compare the rate of effusion of two gases. Graham's Law states that the rate of effusion of a gas is inversely proportional to its molar mass.


rate=1MMgas


This means that when comparing two gases:


rategas 1rategas 2=MMgas 2MMgas 1
