When 50ml of 0.500M HCl at 25C is added to 50ml of 0.500M NaOH at 25C in a coffee cup calorimeter, the temperature of the mixture rises to 28.2C. What is the heat of reaction per mole of acid? Assume the mixture has a specific heat capacity of 4.18 J/gK and that the densities of the reactants are 1.00g/ml.
