The enthalpy change for the dissolution of NH4NO3 is +26.8 kJ/mol. When 40.0 g of NH4NO3 dissolves in 250.0 g of water in a coffee cup calorimeter, what will the final temperature of a solution be if it was initially at 25.0 °C? Assume that the heat capacity of the solution is the same as the specific heat of pure water, 4.184 J/(g·K). Hint: don't forget to add the masses of solute and solvent.
