Concentration in mol dm⁻³
Concentration in mol dm⁻³
Concentration tells you the amount of solute dissolved in each unit volume of solution. A concentration of 0.50 mol dm−30.50 \, \text{mol dm}^{-3}0.50mol dm−3 means that each dm3\text{dm}^3dm3 of solution contains 0.500.500.50 mol of solute.
Step-by-step lessons on Edexcel GCSE Chemistry 6.2.1 Concentration in mol dm⁻³ and titration calculations. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
