Calculate ΔH (in kJ/molkJ/mol NH₄NO₃) for the solution process. NH₄NO₃(s) → NH + 4(aq) + NO₃⁻(aq) Assume that the specific heat of the solution is the same as that of pure water. Express your answer to two significant figures and include the appropriate units. When a 4.25-g sample of solid ammonium nitrate dissolves in 60.0 g of water in a coffee-cup calorimeter, the temperature drops from 22.0 ᵒC to 16.9 ᵒC.
