When 50.0 mL of 0.400 mol L-1 Ca(NO3)2 is added to 50.0 mL of 0.800 mol L-1 NaF, CaF2 precipitates, as shown in the net ionic equation below. The initial temperature of both solutions is 23.0 °C. Assuming that the reaction goes to completion, and that the resulting solution has a mass of 100.00 g and a specific heat of 4.18 J g-1°C-1, calculate the final temperature of the solution.

Ca2+(aq) + 2 F-(aq) → CaF2(s) ΔrH = -11.5 kJ

◦ 22.45 °C
◦ 23.55 °C
◦ 24.10 °C
◦ 24.65 °C
