Problem

A 0.465 gram sample of a compound containing only the elements carbon, hydrogen, and oxygen is burned in an analytical combustion train. This combustion produces 1.16 grams of carbon dioxide and 0.571 grams of water. Calculate the empirical formula of this compound based on this combustion information. Atomic Masses: C=12.0 H=1.00 O=16.0 amu

Historically, the absorbtion of carbon dioxide in a combustion train analysis was performed in Justus Liebig's kaliapparat - circa 1831. The inclusion of the kaliapparat on the modern American Chemical Society symbol is a mark of the historical importance of the above calculation.
