Question

The propane fuel(C3H8) used in gas barbecues burns according to the following equation:
C3H8(g) + 5O2(g) --> 3CO2(g) + 4H2O(g)
∆Ho rxn = -2044kj
If a pork roast must absorb 2200 kj to fully cook, and if only 10% of the heat produced by the barbecue is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast?

thanks
