Calculate the enthalpy change of dissolution (in kJ/mol) for NaCl in water, given that 1.00 g of NaCl is dissolved in 50.0 mL of water at 25°C. The density of water is 0.997 g/mL and the specific heat capacity of the solution is assumed to be the same as that of water (4.184 J/gK). The molar mass of NaCl is 58.44 g/mol.
