State water is an endothermic process

Reference no: EM13174101

Dissolving NH4NO3 in water is an endothermic process. In fact, this reaction is often used in cold packs sold at the drug store. When 23.8 g of NH4NO3 was rapidly dissolved in 79.5 mL of water in a coffee cup calorimeter, the temperature dropped from 27.7 °C to 11.0 °C. Assuming that the specifc heat of the solution is 4.184 J g-1 °C-1 and that the solution was isolated from the surroundings, calculate the heat absorbed by the reaction in kJ per mole of NH4NO3.
