(a)
Interpretation:
The overall mole fraction of aniline in the given mixture has to be determined.
Concept introduction:
A mole fraction of a molecule in a mixture is the ratio of number of moles of particular molecule to the sum of number of moles of all molecules in the mixture. Equation for mole fraction of a molecule in a mixture of three molecules (A, B and C) is,
The lever rule is mainly used to determine compositions of phases and the relative proportions of phases to each other in Binary diagrams of compounds and using the lever rule we can determine quantitatively the relative composition of a mixture in a two phase region in a phase diagram.
According to lever rule, we can write,
The total amount of A in the sample is
Thus,
(a)

Explanation of Solution
Given,
Aniline and hexane form partially miscible liquid-liquid mixtures at temperatures below
Now, the mole fractions of aniline in this mixture can be determined,
(b)
Interpretation:
The relative amounts of two phases in the given mixture has to be determined using lever rule.
