Show how to solve:

The determination of the heat of neutralization for HCl was determined, using a calorimeter having a calorimeter constant of 85.0 J/°C. To this calorimeter, 50.0 mL of 2.100 M HCl were added to 50.0 mL of 2.210 M NaOH. The temperature rose from 25.0 °C to 35.0 °C. The specific heat of the mixture is 5.02 J/g°C. The density of the mixture is 1.02 g.cm-3. What is the heat of neutralization for HCl in kJ/mol? (Answer -56.9 kJ/mol)
