Ethanol is being used more and more as a car fuel. The standard enthalpy change of formation of carbon dioxide is $-393\,\text{kJ mol}^{-1}$. The standard enthalpy change of formation of water is $-286\,\text{kJ mol}^{-1}$. The standard enthalpy change of formation of ethanol is $-277\,\text{kJ mol}^{-1}$. Calculate the standard enthalpy change of combustion of ethanol.
