97: The propane fuel (C3H8) used in gas barbecues burns according to the equation: C3H8(g) + 502(8) -> 3CO2(g) + 4H2O(g) dHrxn = -2044 kJ. If a pork roast must absorb 1.6*103 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? %3D
