Empirical Formulas and the Solid State: A Proposal William B. Jensen This brief article calls attention to the failure of most introductory textbooks to point out explicitly the fact that nonmolecular solids do not have molecular formulas and suggests some practical remedies for improving textbook coverage of this subject. The inadequacies of the terms "empirical formula" and "molecular formula" are also discussed, and the terms "relative compositional formula" and "absolute compositional formula" are proposed as more appropriate alternatives.

Chemical equations are actually matrix equations Alberty, Robert A. Chemists tend to think that chemical equations are unique to chemistry and they are not used to thinking of chemical equations as the mathematical equations they in fact are. The objective of this paper is to illustrate the mathematical significance of chemical equations. Alberty, Robert A. J. Chem. Educ. 1991, 68, 984.
