Adding 4.88 g of NH4NO3 (s) to 140 g of water in a coffee-cup calorimeter (with stirring to dissolve the salt) resulted in a decrease in temperature from 19.0 °C to 16.7 °C. Calculate the enthalpy change for dissolving NH4NO3 (s) in water in kJ/mol. Assume the solution (whose mass is 144.9 g) has a specific heat capacity of 4.2 J/g. K. (Cold packs take advantage of the fact that dissolving ammonium nitrate in water is an endothermic process.) ACE A cold pack uses the endothermic enthalpy of a solution of ammonium nitrate.
