Problem 5.56 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 Degree C to 16.9 Degree C. Part A Calculate Delta H (in kJ/mol NH4NO3) for the solution process NH4 NO3 (s) right arrow NH4+ (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 figure and include the appropriate units. Part B Is this process endothermic or exothermic? Endothermic exothermic
