An herbicide contains only C , H, Cl, and N. The complete combustion of a 150.0 mg sample of the herbicide in excess oxygen produced 156.9 mL of CO2 and 91.52 mL of H2O vapor at STP. A separate analysis determined the 150.0 m sample contained 41.36 mg Cl. Determine the percent composition of the herbicide. Determine the empirical formula of the herbicide. The herbicide has a molar mass of 257.16 g/mol. What is the molecular formula of the herbicide?
