Mole fraction:
The mole fraction of a component in a mixture is defined as the ratio of the number of moles of the component to the total number of moles of all the components in the mixture.
i.e.,
$\text{Mole fraction of a component}=\frac{\text{Number of moles of the component}}{\text{Total number of moles of all components}}$
Mole fraction is denoted by ‘x’.
If in a binary solution, the number of moles of the solute and the solvent are nA and nB respectively, then the mole fraction of the solute in the solution is given by,
$\text{x}_\text{A}=\frac{\text{n}_\text{A}}{\text{n}_\text{A}+\text{ n}_\text{B}}$
Similarly, the mole fraction of the solvent in the solution is given as:
$\text{x}_\text{B}=\frac{\text{n}_\text{B}}{\text{n}_\text{A}+\text{ n}_\text{B}}$
