The empirical formula of compound X should be calculated. Concept introduction: The empirical formula is obtained with the help of simple molar ratio of each element in a compound. The given compound X needs to be analyzed on the basis of products obtained and the simple mole ratio of each elements need to be determined to find the correct empirical formula. Given: Compound X contains nitrogen, oxygen, carbon, hydrogen and chlorine only. 1.00g of compound X produces 1.95 g of solid AgCl upon reaction with excess AgNO 3 . 1.00g of compound X upon combustion produces, 0.900g of CO 2 and 0.735g of H 2 O. To determine: Empirical formula of compound X
