Two students perform an experiment to determine the molar enthalpy of sucrose (C HO, molar mass = 342 / ). A total of 8.8g glucose is placed in a bomb calorimeter containing 19.4 g water. The glucose is combusted with excess oxygen. The molar heat of combustion of glucose is 5600 J/mol. The specific heat of water is 4.2 J g C . What will be the change in temperature experienced by the water?
