Assume 100 g of this compound
mass O = 69.54 g
moles O = 69.54 g / 15.999 g/mol= 4.347
mass N = 30.46 g
moles N = 30.46 g / 14.0067 g/ml= 2.175
the ratio between O and N is 4.347/ 2.175 = 2
N O2 = empirical formula
NO2 ( molar mass = 46 g/mol)
92/ 46 = 2
multiply by 2 the empirical formula to get the molecular formula N2O4
