When 1.045 g of CaO, MM = 56.08 g mol^-1, is added to 50.0 mL of water at 25.0 degree C in a calorimeter, the temperature of the water increases to 32.3 degree C. Assuming that the specific heat of the solution is 4.18 J g^-1 degree C^-1, the density of water is 1.00 g mL^-1, and that the calorimeter itself absorbs a negligible amount of heat, calculate Delta H in kilojoules mol^-1 for CaO based on the following balanced reaction: CaO(s) + H_2O(l) rightarrow Ca(OH)_2(aq)
