    1. The problem statement, all variables and given/known data
    a mixture of methane (CH4) and ethane (C2H6) of mass 13.43 g is completely burned in oxygen. If the total mass of CO2 and H20 produced is 64.84 g, calculate the fraction of methane in the mixture.

    2. Relevant equations

    3. The attempt at a solution
    I have absolutely no idea :/
