Q5(b). Empirical formula of a C, H, N, Cl compound
A compound X contains only carbon, hydrogen, nitrogen and chlorine. When 1.00 g of X is dissolved in water and allowed to react with excess AgNO₃, a mass of AgCl [given in the paper] is collected. When 1.00 g of X is subjected to complete combustion, 0.900 g of CO₂ and 0.735 g of H₂O are formed. What is the empirical formula of X?
