The following acid-base reaction is performed in a constant pressure calorimeter. H+ (aq) + OH-(aq) ? H2O (l) ?H=-57. 32 kJ/mol The temperature of 1000.0 g of water rises from an initial temperature of 24.5 °C to a final temperature of X °C when 1 mole of H+ reacts with an excess of OH- within the calorimeter. The specific heat of water is 4.18 J/g·°C. Assume the heat capacity of the calorimeter is negligible. Calculate X, the final temperature or the water
