Calculation Of Percentage Feed Left Over As Liquid And Vapor

Question

A liquid mixture containing 50 mole% n-heptane and 50 mole% n-octane is subjected to a differential distillation at atmospheric pressure until the residual liquid contains 30 mole% n-heptane. Using the equilibrium data determine the percentage of feed that is left over as residue. x and y are mole fractions of benzene in liquid and vapor.

 
x    0.50    0.46    0.42    0.38    0.34    0.32       
y    0.69    0.65    0.61    0.57    0.52    0.49

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
