Using a coffee cup calorimeter, 3.15 g of ammonium chloride, NH4Cl is added
100.0 g of water at 25.0 °C, the temperature of the water drops down to 21.9
°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)
A
