Question: If 1.32 g MgO is combined with 100.0 mL of 1.00 M HCl in a coffee cup calorimeter, the temperature of the HCl solution increases

If 1.32 g MgO is combined with 100.0 mL of 1.00 M HCl in a coffee cup calorimeter, the temperature of the HCl solution increases from 24.2 0 C to 34.4 0 C. Calculate the enthalpy change for the reaction per mole of MgO. Assume that the specific heat of the HCl solution is 4.18 J/gK and its density is 1.00 g/mL and no heat is lost to surroundings.
MgO (s) + 2 HCl (aq) →  MgCl 2 (aq) + H 2 O ( l )
