Mass Percent Calculator
Calculate mass percent (w/w%) of a solution. Mass percent = (mass of solute / mass of solution) x 100
Mass Percent: (mass solute / mass solution) x 100
Common Concentrations:
Mass Percent
10.0000%
Mass of Solute
10.0000 g
Mass of Solution
100.0000 g
Mass of Solvent
90.0000 g
Solute:Solvent Ratio
0.1111
Formula:
Mass % = (Mass of Solute / Mass of Solution) x 100
What is Mass Percent?
Mass percent (also called weight percent or w/w%) is a way of expressing the concentration of a component in a mixture or solution. It represents the ratio of the mass of the solute to the total mass of the solution, multiplied by 100. This concentration unit is widely used in chemistry, pharmacy, and industry because it is independent of temperature and easy to measure.
