Determine the standard enthalpy change of the dissolution reaction of 2.50 g of NaOH in water, given that the molar enthalpy of hydration of Na+ and OH- ions are -406.8 kJ/mol and -230.0 kJ/mol respectively. The heat capacity of the calorimeter is 25.2 J/°C and the initial and final temperatures were 24.0°C and 29.2°C respectively.

Calculate the standard enthalpy change for the reaction where 250 mL of 2M HCl is mixed with 500 mL of 1M NaOH, assuming that the specific heat capacity of the resulting solution is 4.18 J/g°C and the density of the solution is 1.00 g/mL. (Hint: The balanced chemical equation for the reaction is HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l))
