Two solutions namely, 500mL of .50 M HCl and 500 mL of .50 M NaOH at the same temperature of 22.1 *C are mixed in a constant-pressure calorimeter. The heat capacity of the calorimeter was 250 J / *C. Given that the specific heat of the solution is 4.184 J/g*C, the density of the solution is 1.00 g/mL, and that the heat of neutralization for the process H+(aq) + OH-(aq) ---> H2O(l) is -56.2kJ, what is the final temperature of the mixed solution?
