Concentration (GCSE Chemistry)

This video aimed at GCSE students, explains the meaning of the term concentration and that concentration is usually expressed in mol/dm3. It also shows how to convert concentrations expressed in mol/dm3 to g/dm3 and concentrations expressed in g/dm3 to mol/dm3. Finally the video explains how to calculate concentrations of solutions in mol/dm3 from given masses of solute and volumes of solution.
