Problem- When 2.825 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 9.550 grams of CO2 and 1.955 grams of H2O were produced. In a separate experiment, the molar mass of the compound was found to be 78.11 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon.
