When 100 G of Solid NH₄Cl Is Dissolved in 25

question 68

Short Answer

When 1.00 g of solid NH₄Cl is dissolved in 25.00 g of water contained in a coffee cup calorimeter, both reagents initially being at 25.0°C, the temperature falls to 22.4°C. Assuming that the heat capacity of the ammonium chloride solution is 4.18 J/(g·K), calculate the heat (enthalpy) of solution of NH₄Cl, (a) in J/g and (b) in kJ/mol.
