1.994 g sample of ethanol, CH3CH2OH, is combusted in a bomb calorimeter. The temperature of the calorimeter increases by 10.91 K. If the heat capacity of the bomb is 615.5 J/K and it contains 1.150 kg of water, what is the enthalpy change per mole of ethanol combusted? The specific heat capacity of water is 4.184 J/g×K and the molar mass of ethanol is 46.07 g/mol.
