Instant cold packs used to treat athletic injuries contain solid NH4NO3 and a pouch of water. When pack is squeezed the pouch breaks and the solid dissolves, lowering the temperature. NH4NO3+H2O yields NH4NO3 heat is +25.7kj. What is the final temp in a squeezed cold pack that contains 44.0g of NH4NO3 dissolved in 125mL of water. Assume specific heat of 4.18 J/gCelcius for solution and an initial temp of 25.6 Celcius, and no heat is transferred from the environment to the cold pack.
