Isotopic Abundances and Atomic Weights: History of IUPAC Commission II.1 in the ­Service of Chemistry

John R. De Laeter
Published Online: 2019-01-07 | DOI: https://doi.org/10.1515/ci-2019-0105


Atomic weights are of fundamental importance in science, technology, trade and commerce. In particular, atomic weights relate mass to molar quantities. It is therefore not surprising that the measurement of atomic weights has played a central role in the development of chemistry and continues to be a key component in the progress of discipline.
