A 51.6-mL dilute sоlutiоn оf аcid аt 23.85°C is mixed with 48.5 mL of а dilute solution of base, also at 23.85°C, in a coffee-cup calorimeter. After the  reaction occurs, the temperature of the resulting mixture is 27.25°C. The density of the final solution is 1.03 g/mL. Calculate the amount of heat evolved. Assume the specific heat of the solution is 4.184 J/g•°C. The heat capacity of the calorimeter is 23.9 J/°C.
