Elemental analysis of the unknown gas from Part A revealed that it is 30.45% N and 69.55% O by mass. What is the molecular formula for this gas?
Express your answer as a chemical formula.
The rate of effusion of a gas, r, is inversely proportional to the square root of its molar mass, M. The relative rate of two different gases is expressed as
where r1 and r2 are the effusion rates of two gases and M1 and M2 are their respective molar masses.
