One hundred kg/hr of a 50 wt% solution of solute C in solvent A is to be extracted at 25 °C in a continuous LLE system with a pure second solvent B to obtain a final raffinate of 5 wt% of C. Using the following equilibrium data, determine the number of counter-current stages required when the mass rate of the extractive solvent B is 25 % of the feed solution.
