solve both questions (withclear & accurate graphing) , please :)

Q2. A Feed that is 40 wt% isopropyl alchohol (IPA), 55 wt% diisopropyl ether (Ether) and 5 wt% Water is mixed with pure water, the solvent, in a LLE cascade to recover the ether (solute). It is required to produce a raffinate stream that is 3wt% isopropyl alcohol, and an extract stream that is 20wt% isopropyl alcohol. The ternary phase diagram for this mixture is provided below: (a) Find S/F [2 points] (b) How many stages are required for this extraction?
