The correct concentration of this solution is 33,3% (m/m)
To calculate the concentration of a solution, it is necessaries to know the amount of solutes and solvents that are presents in the solution.
The concentration is calculated according to the expression below:
[tex]C = \frac{solute (g)}{solvent (g)}[/tex]
The amount of solvent is measured in every 100 grams, to calculate the percentage of solute present. So, considering this, we have:
[tex]\frac{25g}{75g} = \frac{xg}{100g}[/tex]
[tex]x = 33,3g[/tex]
So, the concentration of 25 grams of solute in 75 gramas of solvent is equal to 33,3% (m/m)
