The blue line on the diagram illustrates the effect of using fractional distillation to separate a mixture of hexane (C6H14) and heptane (C7H16). If one starts a fractional distillation with a 0.20 mole fraction of hexane, what is the approximate mole fraction of hexane in the vapor phase after two evaporation condensation cycles?

Can anyone help? I'm not sure what I'm doing wrong but the graph I keep plotting just seems to end up as straight line.
TOPIC: Recrystallization Students were tasked to conduct a recrystallization experiment to test the ability of the three newly discovered solvents in their laboratory to purify and separate a mixture containing compounds X and Y. The solubilities of the two compounds in g/50 mL of hot and cold solvents are given in the table. Given the data, if a mixture containing 9.0 g each of X and Y is to be recrystallized from 100 milliliters of the solvents, what is the best solvent to use? Support your answer by doing a schematic diagram for EACH solvent.
Pre-lab Assignment 1.) Note from the 'Introduction' that the freezing-point-depression constant, Kfp, for any solvent can be calculated as long as the heat of fusion, AHfus, and freezing point of the solvent is known. Calculate the freezing-point-depression constant (in SI units) for carbon tetrachloride, CC14, given that its heat of fusion is 2.5 kJ/mol and its freezing point is 250.3 K.
