2.00 × 102 mL of 0.862 M HCl is mixed with 2.00 × 102 mL of 0.431 M Ba(OH), in a constant-pressure calorimeter of negligible heat capacity. The initial temperature of the HCl and Ba(OH), solution is the same, at 20.48°C.

For the process

H(aq) + OH(aq) → H₂O(l)

the heat of neutralization is -56.2 kJ/mol. What is the final temperature of the mixed solution?
