Combustion Analysis
15PRACTICE PROBLEM
The following data were obtained from experiments to determine the molecular formula of aniline, a precursor of urethane, which is made up only of carbon, hydrogen, and nitrogen. Combustion analysis of 11.65-g gives 7.96 g of H2O and 1.75 g of N2. Aniline has a molar of 93 g/mol. What is the molecular formula of aniline?
