Define 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.
Mole fraction of a component = `("Number of moles of the component")/("Total number of moles of all component")`
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,
`x_A = n_A/(n_A+n_B)`
Similary the mole fraction of the solvent in the solution is given
`x_B = n_B/(n_A+n_B)`
