160 cm³/s of a solvent S is used to treat 400cm³/s of a 10 per cent by mass solution of A in B, in a
three-stage countercurrent multiple-contact liquid-liquid extraction plant. What is the composition
of the final raffinate?
Using the same total amount of solvent, evenly distributed between the three stages, what would
be the composition of the final raffinate if the equipment were used in a simple multiple-contact
arrangement?
