A 50.0 mL solution of 1.2 M HCl at 24.1 degrees Celsius is mixed with 50.0 mL of 1.3 M NaOH, also at 24.1 degrees Celsius, in a coffee cup calorimeter. After the reaction occurs, the temperature of the resulting mixture is 29.8 degrees Celsius. The density of the final solution is 1.05 g/mL. Calculate the molar heat of neutralization. Assume the specific heat of the solution is 4.184 J/g*degrees C. The heat capacity of the calorimeter is 32.5 J/degrees C.
