Abstract | In this study the origin and evolution of the meanings of the concepts 'amount of substance' and ' mole' are described. Serious disagreements about these concepts amongst chemistry teachers and the recommendations of the international scientific community are identified. Attention is also drawn to the didactic implications that these epistemological difficulties may have for the teaching of chemistry. |
