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 that gasoline consists of a mixture of octanes (different isomers of C8H18 ), that the average heat of combustion of C8H18(l) is 5400 kJ/mol , and that gasoline has an average density of 0.70 g/mL . The density of ethanol is 0.79 g/mL . A. How many gallons...
