20.0 mL of NaOH(aq) is titrated against 1.00 M HCl(aq) in a well-insulated vessel with constant stir — Thermochemistry Chemistry Question

20.0 mL of NaOH(aq) is titrated against 1.00 M HCl(aq) in a well-insulated vessel with constant stirring. Each solution is initially at 22.0° C, and the temperature of the reaction mixture is monitored after each 2.0 mL of hydrochloric acid is added. What is ∆H° for the reaction that takes place? Assume that all solutions’ densities and heat capacities are the same as that of pure water, and that solution volumes are additive.
