On the chart itself, clearly mark which fractions you will use for calculating the percent of cyclohexane, which fractions you will use for calculating the percent of toluene, and which fractions are a mixture of the two. Assume the mixture fractions are 50% cyclohexane and 50% toluene. The pot residue (which would have distilled if you had let it), must be included.
