    Write a balanced equation for the combustion of ethane (C2H6). A combustion of a hydrocarbon consumes oxygen and produces water and carbon dioxide:

    2C2H6 + 7O2 --> 4CO2 + 6H2O

    Obtain the mole ratio by looking at the coefficients: every two moles of C2H6 consumed yields 4 moles CO2.

    (1.1 mol C2H6)(4 mol CO2 / 2 mol C2H6) = 2.2 mol CO2

    if you mean by consumed combustion in an adequate volume of dioxygen, then :

    2 C2H6 + 7 O2 ------> 4 CO2 + 6 H2O

    we have : nf(C2H6) = 1.1 - 2 xmax = 0

    so xmax = 0.55 mol

    and we have : nf(CO2) = 4 xmax = 2.2 mol
