Methanol (CH,OH) is used as a fuel in high-performance engines in racecars. Compare the standard enthalpy of combustion per gram of methanol with that per gram of gasoline. Gasoline is actually a mixture of compounds, but assume for this problem that gasoline is pure liquid octane (CH). Compound CH,OH(D) CO....
