1. When 1.629 grams of a hydrocarbon, CxHy, were burned in a
combustion analysis apparatus, 4.991 grams of CO2 and 2.384 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.
