Calculate moles:
Moles of nitrogen: 0.44 g / 14.0 g/mol = 0.03143 mol
Moles of oxygen: 1.12 g / 16.0 g/mol = 0.07 mol
Find the ratio:
Ratio of N to O = 0.03143 / 0.07 = 1:2
Empirical formula:
Empirical formula is NO2.
Molar mass of empirical formula:
Molar mass of NO = 46.0 g/mol.
Determine molecular formula:
92.0 g/mol / 46.0 g/mol = 2, so the molecular formula is N2O4.
