Question

8 g/dm³

Concentration is found using the formula: concentration = mass / volume. Here, concentration = 12 g / 1.5 dm³ = 8 g/dm³.

Confusing Concentration Units

Students often confuse grams per cubic decimetre (g/dm³) with moles per cubic decimetre (mol/dm³) when calculating concentrations.

Always check the units required for the concentration calculation and ensure you are using mass (g) and volume (dm³) for g/dm³.
