Another generator is available that uses gasoline instead, and you find that the local gasoline supply contains Lead $($Pb$).$ The efficiency of this generator is $32\mathrm{.}85\%$ and the heating value of the fuel is $4\mathrm{.}674582\backslash$times $104$ MJ$/$kg$.$ For your calculations, you can assume a composition that is $99\mathrm{.}97$ wt$\%$ octane $($C$8$H$18)$ with the remainder being lead $($Pb$).$

How much fuel do you need? What pollutants are released? What environmental problems might they cause?
