Question

A dilute solution of hydrochloric acid with a mass of 614.86 g and containing 0.33004 mol of HCl was exactly neutralized in a calorimeter by the sodium hydroxide in 619.41 g of a comparably dilute solution. The temperature increased from 15.529 to 19.691°C. The specific heat of the HCl solution was 4.031 J·g-1·°C-1; that of the NaOH solution was 4.046 J·g-1·°C-1. The heat capacity of the calorimeter was 77.99 J·°C-1.

Answer 1

I don't see a question here. I assume you want to calculate the heat of neutralization (in what units?)
