Chemistry

5a. When 4.355 grams of a hydrocarbon,CxHy, were burned in a combustion analysisapparatus, 14.72 grams of CO2 and3.014 grams of H2O were produced.

In a separate experiment, the molar mass of the compound was foundto be 26.04 g/mol. Determine the empirical formulaand the molecular formula of the hydrocarbon.

  • Enter the elements in the order presented in thequestion.
    empirical formula =
    molecular formula =

5b.
A 12.57 gram sample of an organic compoundcontaining C, H and O is analyzed by combustion analysis and17.83 grams of CO2 and10.95 grams of H2O are produced.
