what is mass percentage of a solution?

Mass percentage of a solution is the percentage of the mass of the solute present in a given mass of the solution. It shows how much solute is dissolved in the solution by mass.

Formula:

Mass Percentage = (Mass of Solute ÷ Mass of Solution) × 100

Where:

• Mass of Solute = Substance being dissolved

• Mass of Solution = Mass of solute + Mass of solvent

Example:
If 10 g of salt is dissolved in 90 g of water, the mass of the solution is 100 g.

Mass Percentage = (10 ÷ 100) × 100 = 10%

In simple terms: Mass percentage tells us how many grams of solute are present in every 100 g of a solution.
