Gasoline (Approximated by Octane) Typically Contains 0 $3.5 \mathrm { MJ } / \mathrm { km }$

Gasoline (approximated by octane) typically contains 0.1% sulfur by weight. If a passenger vehicle requires $3.5 \mathrm { MJ } / \mathrm { km }$ of primary energy, calculate the total annual mass of $\mathrm { SO } _ { 2 }$ produced by 250 million vehicles in the United States, each traveling $25,000 \mathrm {~km}$ per year.
