Assuming we have 100 g of sample30.45/MW of N 14g = 2.17569.55/MW of O 16g = 4.344.34/2.185 = 2for every 1 mole of N we have 2 moles of Oso the empirical formula would be NO2 without having the molecular weight of the entire molecule the molecular formula can not be determined with the information in your question
