Suppose 23 °\degree CCalculate The G Δ\Delta H of Solution of NH4Cl in KJ/mol

Question 195

Short Answer

Suppose 23.00 g ammonium chloride 53.491 (g/mol) dissolves in water in a calorimeter to form 100.00 g of solution.The temperature decreases by 10.75 °\degree C.Calculate the Δ\Delta H of solution of NH4Cl in kJ/mol.Assume the specific heats of the solution and of the empty calorimeter are (4.18 J/g . °\degree C) and 0.170 kJ/ °\degree C, respectively.
