Calculate the volume of carbon dioxide at 20.0 degrees C and 0.910 atm produced from the complete combustion of 5.00 methane. Compare your result with the volume of CO2 produced from the complete combustion of 5.00 kg of propane (C3H8). I found the volume of CO2 from 5.00 kg of methane. I was unable to find the volume of CO2 from 5.00 kg of propane.
