Chapter 6, Problem 38P(choose chapter or problem)
A quantity of 85.0 mL of 0.900 M HCl is mixed with 85.0 mL of 0.900 M KOH in a constant-pressure calorimeter that has a heat capacity of \(325\ \mathrm{J} /{ }^{\circ} \mathrm{C}\). If the initial temperatures of both solutions are the same at \(18.24^{\circ} \mathrm{C}\), what is the final temperature of the mixed solution? The heat of neutralization is -56.2 kJ/mol. Assume the density and specific heat of the solutions are the same as those for water.

ANSWER:Step 1 of 6
Heat capacity of the calorimeter can be calculated by the following formula;
Here,
