Question

1 g

The mass of solute can be calculated using the formula: mass = concentration × volume. Here, mass = 2 g/dm³ × 0.5 dm³ = 1 g.

Confusing Concentration Units

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

Always specify whether you are using mass concentration or amount concentration, and ensure you use the correct units for the calculation.
