A 10.03 gram sample of an organic compound containing C, H and O
is analyzed by combustion analysis and 12.73 grams of CO2 and 3.474
grams of H2O are produced. In a separate experiment, the molar mass
is found to be 104.1 g/mol. Determine the empirical formula and the
molecular formula of the organic compound.

When 2.422 grams of a hydrocarbon, CxHy, were burned in a
combustion analysis apparatus, 7.420 grams of CO2 and 3.545 grams
of H2O were produced. In a separate experiment, the molar mass of
the compound was found to be 86.18 g/mol. Determine the empirical
formula and the molecular formula of the hydrocarbon.
