### What is Meant by Mole Fraction?

In chemistry, a mole fraction is a concentration unit which is used to express the concentration of a chemical component. The mole fraction can be calculated by dividing the number of moles of one component of a solution by the total number of moles of all the components of a solution. It is noted that the sum of the mole fraction of all the components in the solution should be equal to 1.
