Exam tips
Master Unit Conversions
Calculate carefully by always convert volumes from cm3 to dm3 before using them in concentration calculations. Link your answer to Concentrations in mol/dm3 and titration calculations in Using concentrations of solutions in mol/dm3 (chemistry only) (HT only), and show formula, substitution, calculation, final answer, and unit where relevant.
This ensures accuracy in your calculations, as concentration in mol/dm3 requires volume in dm3. This prevents Unit 4.3 mistakes such as mixing mass with moles, using the wrong unit, or confusing percentage yield with atom economy.
