Calculate the enthalpy of solution of sodium hydroxide (NaOH) in water, given that the heat absorbed by the solution is 128.0 kJ/mol and the molar concentration of the solution is 0.1 M. Assume that the specific heat capacity of the solution is the same as that of water (4.18 J/g⋅K) and that the density of the solution is 1.00 g/mL.
