The heat of dissolution for solid NH4NO3 is +25.41 kJ mol−1. A 4.02-g sample of solid NH4NO3 dissolves in 67.7 g of water in a coffee-cup calorimeter. If the initial temperature of the water was 23.6 oC, the final temperature of the water will be ___ oC. Assume the specific heat of the resulting solution is 4.18 J g−1 K−1.

The answer is 19.09 but im not sure how they got that
