About Mass Percentage

What is Mass Percentage?

Mass percentage (or mass percent) is the mass of a solute divided by the total mass of the solution, multiplied by 100%. It represents the concentration of a component in a mixture.

Formula

Mass Percent = (Mass of Solute / Mass of Solution) × 100%

Example Calculation

If you dissolve 5g of salt in 45g of water:

Mass of Solute = 5g
Mass of Solvent = 45g
Mass of Solution = 5g + 45g = 50g
Mass Percent = (5g / 50g) × 100% = 10%
