Answer:
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 <em>defined as the mass of a solute divided by the mass of a solution times 100:</em>
<em>%m/m= (mass of a solute/mass of solution)x100</em>
<em>Where the mass of the solution is the sum of the mass of solute and mass of solvent.</em>
%m/m is commonly used when you can measure the masses of both solute and solution.
