Question

2. Cold packs take advantage of the fact that dissolving NH4NO3 in water is an endothermic process. When
5.44 g of solid ammonium nitrate is added to 150.0 g of water in a coffee cup calorimeter, the temperature
of the solution changes from 18.6 °C to a final temperature which you will determine. Calculate the
enthalpy change for dissolving ammonium nitrate in water, in kJ/mol. Assume the specific heat of the
solution is 4.2 J/g·K.
g. Using the value of qsolution, calculate ∆T, as well as the final temperature reached by the solution. 

Expert Solution
Step 1

Answer:

Since, dissolution of NH4NO3 is an endothermic process, therefore heat will be absorbed during its dissolution and that will cause a decrease in the temperature of solution.
