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 J/°C. If the initial temperature of both solutions are the same at 18.24°C, what is the final temperature of the mixed solution ?
The heat of neutralization is -56.2 kJ/mol.
Assume the density (1.00 g/mL) and the specific heat (4.184 J/g°C) of the solution is the same as those for water
Please help. thank u
