Problem 2 answers in units of bar for part b, provide your equilibrium osmotic pressure The osmotic coefficient of a solvent , is defined by G = Gs + RTln(x), where s → 1 as x, → 1: a) Develop an expression relating the activity coefficient ys to the osmotic coefficient s. b), Robinson and Wood (J. Sol. Chem., 1, 481 [1972]) report the following interpolated values for the osmotic coefficient of seawater as a function of concentration at 25°C. I 0.5 1.0 2.0 4.0 6.0 0.9018 0.9155 0.9619 1.0938 1.2536 where I = ₁ z²M₁ is the ionic strength, z; is the valence of the ith ionic species and M, is its molality. For simplicity, seawater may be considered to be a mixture of only sodium chloride and water. Compute the water activity coefficient and the equilibrium osmotic pressure for each of the solutions in the table.
