What is meant by the mass percent concentration of a solution

The mass of a solute divided by the mass of a solution times 100

Explanation:

The concentration of a solution refers to how much of a solute is dissolved in an amount of solvent. To express this concentration exist different methods, the mass percent concentration is one of them and is defined as the mass of a solute divided by the mass of a solution times 100:

%m/m = (mass of a solute/mass of solution) x100

Where the mass of the solution is the sum of the mass of solute and mass of solvent.

%m/m is commonly used when you can measure the masses of both solute and solution.
