(a) A commercial 737 jet transporting 143 passengersand 5 crew members from Kansas City (MCI) to Baltimore (BWI) burned 11,800 lb (about 1700 gallons)of Jet A fuel en route. Jet A fuel is kerosine based,consisting primarily of CnH2n+2 hydrocarbons, withn: 5 6 to 16, so the carbonhydrogen ratio is close to12. During this flight, how much CO2 was releasedinto the atmosphere? Assume the combustion of thefuel was complete, so all the fuel was burned to formCO2 and H2O. Give both the mass of CO2 produced(in kg and in lbs) and the volume it would occupy at298 K, 1 atm.(b) How much CO2 would be released into the atmosphere if those passengers and crew made the tripinstead, in pairs, in hybrid cars at 40 miles per gallon.Assume the density of the gasoline is 0.75 kg L21andthat carbon and hydrogen dominate the compositionin a ratio of 1:2. The road trip is 1082 miles.
