Fuel is a mixture of different hydrocarbon compounds containing only hydrogen and oxygen. Calculate the volume of carbon dioxide, at 300 °C and 100 kPa, passing through a vehicle's exhaust during the combustion of a full tank of fuel (that is, 50 kg). To simplify the problem, assume that the formula for fuel is C7H16.
C7H16 + 11O2 ? 7CO2 + 8H2O
