A quantity of 2 x 102 mL of 0.862 Molar HCl is mixed with 2 x 102 mL of 0.431Molar Ba(OH)2 in a constant pressure calorimeter that has a heat capacity of 453 J/oC.

The initial temperature of the HCl and Ba(OH)2 solutions is the same at 20.48oC. For the process

H+(aq) + OH-(aq) --> H2O(L)

the heat of neutralization is -56.2 KJ.

What is the final temperature of the mixed solution?
