An herbicide is found to contain only C, H, N, and Cl. The complete combustion of a 100.0-mg sample of the herbicide in excess oxygen produces 83.16 mL of CO2 and 73.30 mL of H2O vapor at STP. A separate analysis shows that the sample also contains 16.44 mg of Cl.

(a) Determine the percent composition of the substance.

(b) Calculate its empirical formula.

(c) What other information would you need to know about this compound to calculate its true molecular formula?
