    Please see the attached file for the fully formatted problem(s).

    A liquid feed consisting of 1200 gmoles of mixture containing 30% naphthalene and 70% dipropylene glycol is differentially distilled at 100 mm Hg pressure and final distillate contains 55% of the feed solution. The VLE data are
    x 8.4 11.6 28.0 50.6 68.7 80.6 88
    y 22.3 41.1 62.9 74.8 80.2 84.4 88

    a. Determine the amount of distillate
    b. Determine the concentration of naphthalene in residue and distillate
