Chapter 1, Problem 1A.13E

Interpretation Introduction

Interpretation:

Mole fractions of the molecules of a mixture that contains $\text{56 g}$ of Benzene and $\text{120 g}$ of toluene has to be calculated.

Concept Introduction:

Mole fractions:

The number of moles of sample is divided by total mole to give mole fraction of sample that present in given mixture.

For example, mole fraction of A in AB mixture is,

    $\begin{array}{l}{\text{x}}_{\text{A}}\text{=}\frac{{\text{n}}_{\text{A}}}{{\text{n}}_{\text{A}}{\text{+n}}_{\text{B}}}\\ \text{Where,}\\ {\text{x}}_{\text{A}}\text{-}\text{mole}\text{fraction}\text{of}\text{A}\\ {\text{n}}_{\text{A}}\text{-}\text{number}\text{of}\text{mole}\text{of}\text{A}\\ {\text{n}}_{\text{B}}\text{-}\text{number}\text{of}\text{mole}\text{of}\text{B}\end{array}$
