What is the mole?

Abstract

The mole is a difficult concept. Surveys have shown that even many teachers do not have a proper understanding of it. To help to meet this problem, the SI/IUPAC formulation of the mole is carefully presented and explained. New SI proposals are also briefly discussed.

Keywords

Amount of substance Chemical amount Mole Number of entities Avogadro constant Avogadro number Stoicheiometry 

Notes

Acknowledgments

I am grateful to Dr. Chris Botton for encouraging me to write this paper and to Professor Brian P. Leonard for drawing my attention to the new SI proposals.
