SI for Chemists: Persistent Problems, Solid Solutions
Hi-Res PDF
Abstract
For chemists there are two persistent difficulties with SI, difficulties that lie at the heart of chemical logic and are notably non-trivial; they are unit(s) of mass and "amount of substance". These difficulties are analyzed and solutions proposed.

Andrzej BarańskiJournal of Chemical Education2012 89 (1), 97-102The Atomic Mass Unit, the Avogadro Constant, and the Mole: A Way To Understanding
Andrzej BarańskiJournal of Chemical Education2012 89 (1), 97-102Numerous articles have been published that address problems encountered in teaching basic concepts of chemistry such as the atomic mass unit, Avogadro’s number, and the mole. The origin of these problems is found in the concept definitions. If these ...
