35. Solving a chemistry problem

4. Integral heat of dissolution of NH4CI ∆Hsol = 15.11 kJ/mol. When 1.473 g of salt was dissolved in 528.5 g of water, the temperature dropped by 0.174 C. The specific heat capacity of the solution is 4.11 (J / g * deg). Determine the thermal constant of the calorimeter.
