200 mL of 1.00M NaOH is reacted with 200 mL of 1.00 M HCl in a calorimeter. The calorimeter and the solutions were at an initial temperature of 19.5oC before mixing. After mixing, the temperature rose to 25.8oC. Assume that the density of all solutions is 1.00 g/mL and the specific heat of the mixed solution is 4.18 J/goC. What is the heat of neutralization of 1 mol of hydrochloric acid?
