How much heat energy is produced when 31.6 grams of propane are burned?

I asked my teacher and she said it would be a stochiometry problem but im still confuded:/

    Yes. I wondered if confuded was a new word I should learn.
    I think the problem is a stoichiometry problem IF you know the heat of combustion. Do you know that? If so, then
    C3H8 + 5O2 ==> 3CO2 + 4H2O
    So it takes 44 g C3H8 to generate ??kJ (the heat of combustion generally given in kJ/mol), then
    heat produced by 44 g = ?? kJ x (31.6/44) =
