In chemistry, the mole fraction is defined as the amount of a constituent divided by the total amount of all constituents in a mixture :
The sum of all the mole fractions is equal to 1:
The mole fraction is also called the amount fraction. It is identical to the number fraction, which is defined as the number of molecules of a constituent divided by the total number of all molecules . It is one way of expressing the composition of a mixture with a dimensionless quantity (mass fraction is another). The mole fraction is sometimes denoted by the lowercase Greek letter (chi) instead of a Roman . For mixtures of gases, IUPAC recommends the letter .
