Question:

Aniline, a starting compound for urethane plastic foams, consists of C, H, and N. Combustion of such compounds yields CO2, H2O, and N2 as products. If the combustion of 9.71 mg of aniline yields 6.63 mg H2O and 1.46 mg N2, what is its empirical formula? The molecular mass of aniline is 93 amu. What is its molecular formula?
