If you have the molar mass, you can find the molecular formula. However, I think the question should be 74% Oxygen and 26% Nitrogen. This will give you an empirical formula NO2. 5 which is the empirical formula of N2O5, a real compound.

For example, one atom of magnesium weighs 24.31 amu (atomic mass units). However, one mole of magnesium weighs 24.31 g. (Moles were planned that way!) Since one mole of MgCl2 consists of one mole of magnesium and two moles of chlorine, the mass of one mole of MgCl2 must be the sum of the masses of the elements.

The molecular formula for ammonia is NH3 . In a molecular formula, the subscript for each element indicates the number of atoms of each element. When there is no subscript written, it is understood to be 1. In one molecule of NH3 , there is 1 atom of N and 3 atoms of H , for a total of 4 atoms.
