When 2.00 g of NaOH is added to 50.0 ml of 1.0 M HCl solution in a constant pressure calorimeter, the temperature increased by 13.1oC. Calculate the heat of neutralization in KJ/mol. (S.H.C. for the solution is 4.18 J/K.g, assume the calorimeter does not absorb any heat and the density of the solution is 1.0 g/mL).
