Question 5 6 pts Using a coffee cup calorimeter, 3.98 g of ammonium clioride, NH4Cl is added 100.0 g of water at 25.0 °C, the temperature of the water drops down to 21.6 °C as the ammonium chloride dissolves. Assume that mass of the solution is equal to the mass of the ammonium chloride and the mass of the water. Also assume that the specific heat of the solution is 4.18 J/g*K. Calculate the enthalpy change (AH rxn) in kJ/mol of ammonium chloride for the energy change that accompanies this dissolving process. Find AH of: NH4CI(s) -->NH4+ (aq) +Cl(aq) (The enthalpy of dissolving)
