Answer 2

Calculating the Mass of the Dissolved Substance in a 25% Solution

To find the mass of the dissolved substance in a 250g solution with a mass fraction of 25%, we can use the formula:

Mass of dissolved substance = Mass of solution × Mass fraction

Substituting the given values: Mass of dissolved substance = 250g × 25%

Calculation

Mass of dissolved substance = 250g × 0.25 = 62.5g

So, the mass of the dissolved substance in the 250g solution with a mass fraction of 25% is 62.5 grams.
