Calculate the standard enthalpy change for the neutralization reaction of hydrochloric acid (HCl) with sodium hydroxide (NaOH) when 50.0 mL of 1.0 M HCl reacts with 50.0 mL of 1.0 M NaOH in a constant pressure calorimeter. Assume the density of the final solution is the same as that of pure water (1 g/mL) and that the specific heat capacity of the final solution is 4.18 J/g K.
