Homework; The equilibrium of a solute C between solvent A & B (upto 30% of C in solution of A) is given by Y = 3.75X, where X & Y are concentration of C in A & B, respectively (both in mass ration unit). Calculate the amount of solvent B required to separate 95% of C from 100 kg of a 15% (by mass) solution of C in A for following separation schemes: (a) an ideal single stage contact & (b) three stage cross current contact
