You measure Ksp for borax and find it to be 6.2 x 10-3 at 22.8°C. If the standard enthalpy change, ΔH°, for the dissolution of borax is 58 kJ, calculate the standard entropy change, ΔS°, (in J/K) for the dissolution of borax at this temperature. (Assume ΔH° is independent of temperature.)

Use dG = -RT*lnK and calculate dG.
Then dG = dH - TdS.
Then dG = dH - TdS.
