The automobile fuel called E85 consists of 85% ethanol and 15%gasoline. E85 can be used in so-called flex-fuel vehicles (FFVs),which can use gasoline, ethanol, or a mix as fuels. Assume thatgasoline consists of a mixture of octanes (different isomers ofC8H18), that the average heat of combustion of C8H18(l) is 5400kJ/mol, and that gasoline has an average density of 0.70 g/mL. Thedensity of ethanol is 0.79 g/mL.
Part A: By using the information given, calculate the energyproduced by combustion of 1.5 L of gasoline.
Part B: By using the information given as well as data inAppendix C, calculate the energy produced by combustion of 1.5 L ofethanol. Consider that water is in the gaseous state.
