Combustion Analysis (Empirical/Molecular Formula)

(1/1)

TheBlackBrainiac:
The combustion of 49.14 grams of a compound that contains only C, H, N, and O yields 84.49 grams of CO2
and 27.65 grams of H2O.
Another sample of the compound with a mass of 96.72 grams is found to contain 24.18 grams of O. What is the empirical formula of the compound?

sjb:
Any thoughts of your own? How many moles of carbon were there in the sample?
