Combustion Analysis (Empirical/Molecular Formula)
« on: January 08, 2019, 04:15:11 PM »

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?

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