When 6.974 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 21.12 CO2 and 10.81 grams of H2O were produced. In a separate experiment, the molecular weight of the compound was found to be 58.12 amu. Determ empirical formula and the molecular formula of the hydrocarbon. Enter the elements in the order presented in the question. empirical formula = molecular formula =
