Calculate the standard enthalpy change (∆H°) for the reaction between 50.0 mL of 0.100 M hydrochloric acid (HCl) and 50.0 mL of 0.100 M sodium hydroxide (NaOH), given that the temperature change was -5.01°C and the specific heat capacity of the solution is 4.18 J/g°C. The balanced chemical equation for the reaction is:

HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

Note: Assume the density of the solutions is 1.00 g/mL and that the specific heat capacity of the solutions is the same as that of water.
