Mole fraction Mole fraction In chemistry, the mole fraction or molar fraction (x) is defined as the amount of a constituent (expressed in moles), "n", divided by the total amount of all constituents in a mixture (also expressed in moles), "n": The sum of all the mole fractions is equal to 1: The same concept expressed with a denominator of 100 is the mole percent or molar percentage or molar proportion (mol%). 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 "N" divided by
