he propane fuel (C3H8) used in gas BBQs burns according to this thermochemical equation:

C3H8 + 5O2 --> 3CO2 + 4H2O delta H = -2217kJ

If a pork roast must absorb 1.6x10^3 kJ to fully cook, and if ONLY 10% of the heat produced by the BBQ is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast.
