Question

4 dm³

Volume can be calculated using the rearranged formula: volume = mass / concentration. Here, volume = 32 g / 8 g/dm³ = 4 dm³.

Confusing Concentration Units

Students often confuse mass concentration (g/dm³) with amount concentration (mol/dm³) when calculating concentration.

Always identify whether you are working with mass concentration or amount concentration, and use the appropriate formula for calculations.
