When 10.1 g CaO is dropped into a styrofoam coffee cup containing 157 g H2O at 18.0°C, the temperature rises to 35.8°C. Calculate the enthalpy change of the following reaction in kJ/mol CaO. Assume that the cup is a perfect insulator and that the cup absorbs only a negligible amount of heat? (the specific heat of water = 4.18 J/g·°C) CaO (s) + H2O (l) → Ca(OH)2 (s)
