E-85 is an alternative fuel for automobiles and light trucks that consists of 85.0% (by volume) ethanol (C2H5OH), and 15.0% gasoline. When ethanol burns completely it produces CO2 and H2O. The balanced equation for the burning of ethanol isC2H5OH+3O2-->2CO2+3H2OThe density of ethanol is 0.790 g/mL. How many moles of carbon dioxide are produced by the complete combustion of the quantity of ethanol in 8.00 gallons of E-85 fuel? _mol CO2
