22.9 mL of an unknown acid was neutralized by mixing it with 50.3 mL of NaOH in an aqueous solution. The final temperature of the solution was 35.2 °C. The initial temperature of the acid and base was 22.0 °C. Assuming that the density of the solution is 1.00 g/mL and the specific heat is 4.184 J/g°C, what is the heat of neutralization reaction?
