Please help me understand the answer of this question. Thank
you.
A countercurrent extraction plant is used to extract acetone from its mixture with water by means of methyl isobutyl ketone (MIK) at a temperature of 25°C. The feed consists of 40 percent acetone and 60 percent water. Pure solvent equal in mass to the feed is used as the extracting liquid. How many ideal stages are required to extract 99 percent of the acetone fed? (Determine stages using triangular diagram.)
