Final answer:

To calculate the enthalpy of solution per mole of NH4NO3, we can use the molar heat of solution of NaOH as a reference.

Step-by-step explanation:

To calculate the enthalpy of solution per mole of NH4NO3, we can use the given molar heat of solution for NaOH as a reference. In Example 17.13.1, the molar heat of solution of NaOH is -44.51 kJ/mol

In this experiment, 50.0 g of NaOH is dissolved in 1.000 L of 20.0°C water. Assuming no heat loss, we can calculate the final temperature of the water using the equatio

q = mCΔT

By substituting the given values, we can solve for q and then convert the value to kJ/mol by dividing by the number of moles of NH4NO3.
