Shouldnt that 6.63 mg be converted to grams before using that formula to get g hydrogen?
Chemistry- Empirical Formula
I'm a little confused about how to convert 6.63 mg H2O to mg H. And calculating mg C as well.

@DrBob222 Yes it is part of the same problem
Chemistry- Empirical Formula
Aniline, consists of C, H, and N. Combustion of such compounds yields CO2, H2O, and N2. If the combustion of 9.71 mg of aniline yields 6.63 mg H2O and 1.46 mb N2, what is the empirical formula? What is the molecular formula of a compound with the molecular weight of 372.504 am...
