(7) Problem 4-17 (15 points) Gasoline (approximated by octane) typically contains 0.1% sulfur by weight. If a passenger vehicle requires 3.5 MJ/km of primary energy, calculate the total annual mass of SOz produced by 250 million vehicles in the United States, each traveling 25,000 km per year.
Gasoline has an energy density = 45 MJ/kg 1 vehicle 1 km energy required = 3.5 MJ = 3.5/45 kg gasoline 250 times 10^6 vehicle 25000 km energy required = 3.5/45 times 250 times 10^6 times 25000 = 4.86 times 10^11 kg % Sulfur produce Total Sulfur = 4.86 times 10^11 times 0.1/100 = 4.86 times 10^8 kg
