When 11.55 grams of ammonium nitrate (NH4NO3) are dissolved in 100.0 grams of water at 25.0 °C in an insulated container, the temperature of the water decreases to 17.06 °C. Assuming that the specific heat of the solution is 4.184 J/(g °C) and that no heat is gained or lost by the container, what is the AH of solution of NH4NO3 in kJ/mol?
