What Is a Mass Fraction?

Mass fraction refers to the ratio of the mass of the solute in the solution to the mass of the solution. Also refers to the percentage of the total mass of a substance in a compound. The mass fraction can also refer to the ratio of the relative atomic mass (multiplication factor) of each atom in the compound to the total formula, that is, the proportion of an element in a substance [1] .

The relationship between the mass fraction and the mass concentration of the substance:
C * M = 1000 * * That is, the quantity concentration of a substance times the molar mass is equal to 1000 times the density times the mass fraction.
c = (V · · / M) / V = V · · / MV = 1000 · / M
= cM / 1000 [2]
