When 6.104 grams of a hydrocarbon, CxHy, were burned in acombustion analysis apparatus, 19.15 grams of CO2 and 7.842 gramsof H2O were produced. In a separate experiment, the molar mass ofthe compound was found to be 28.05 g/mol. Determine the empiricalformula and the molecular formula of the hydrocarbon.
