5a. When 4.355 grams of a hydrocarbon,
CxHy, were burned in a combustion analysis
apparatus, 14.72 grams of CO2 and
3.014 grams of H2O were produced.
In a separate experiment, the molar mass of the compound was found
to be 26.04 g/mol. Determine the empirical formula
and the molecular formula of the hydrocarbon.

5b.
A 12.57 gram sample of an organic compound
containing C, H and O is analyzed by combustion analysis and
17.83 grams of CO2 and
10.95 grams of H2O are produced.
In a separate experiment, the molar mass is found to be
62.07 g/mol. Determine the empirical formula and
the molecular formula of the organic compound.
