Mole fraction is another way of expressing the concentration of a solution or mixture. It is equal to the moles of one component divided by the total moles in the solution or mixture.

a = the component that is being identified for mole fraction

Mole fraction is used in a variety of calculations, but most notably for calculating partial pressures.
