Question

5 dm³

Using the formula: volume = mass / concentration. Here, mass = 25 g and concentration = 5 g/dm³, so volume = 25 g / 5 g/dm³ = 5 dm³.

Common Mistake in Volume Calculation

Students often forget to convert the volume from cm³ to dm³ when calculating the volume of a solution from mass and concentration.

Always convert cm³ to dm³ by dividing by 1000 before using the concentration formula.
