About Mass Percent

Mass percent (also called mass percentage or weight percent) is the mass of a component divided by the total mass of the mixture, multiplied by 100.

Mass % = (Mass of Component / Total Mass) × 100

Common applications:

  • Element in compound: Mass % of each element in a chemical compound
  • Solute in solution: Concentration of solute in a solution
  • Component in mixture: Composition of mixtures and alloys

Mass percent is widely used in chemistry, materials science, and industrial applications to express composition and concentration.
