Calorimetry

The enthalpy of neutralization of a newly discovered compound, HX, was determined using a styroball calorimeter. The calorimeter was first calibrated using 13.00 mL of 0.104 M HCl and 11.29 mL of 0.125 M KOH (AH = -55.85 kJ/mol) and a temperature rise of 4.6 °C was recorded. Using the same calorimeter, 7.58 mL of 0.151 M of HX was reacted with 9.60 mL of 0.125 M NaOH and the temperature changed from 25.9 °C to 23.4 °C.
a. What is the heat capacity of the calorimeter?
b.What is the experimental enthalpy (in kJ/mol) for the neutralization reaction
between HX and NaOH?
I just need someone to explain how can I compute both questions and then I will be up for the rest. Thank you very much.
