    The combustion reaction is as expressed,

    CxHy + O2 - - > CO2 + H2O

    The mass fraction of carbon in CO2 is 3/11. Hence,

    mass of C in CO2 = (3.14 g) (3/11) = 0.86 g C.

    Given that we have 1 g of the hydrocarbon, the mass of H is equal to 0.14 g.

    moles of C = 0.86 g C / 12 g = 0.0713

    moles of H = 0.14 g H / 1 g = 0.14

    The empirical formula for the hydrocarbon is therefore, CH₂.
