The following table gives mole % acetic acid in aqueous solutions and in the
equilibrium vapor at the boiling point of the solution at 1.013 bar.
118.1 113.8 107.5 104.4 102.1 100.0 B.P.,oC
Mole % of acetic acid
100 90.0 70.0 50.0 30.0 0 In liquid
100 83.3 57.5 37.4 18.5 0 In vapor
Calculate the minimum number of theoretical plates for the column required to
produce an initial distillate of 28 mole % acetic acid from a solution of 80 mole %
acetic acid.


i can only draw a grap liquid vs vapor but not sure how to do calculations.can someone enlighten me pls
