Revisiting Molar Mass, Atomic Mass, and Mass Number: Organizing, Integrating, and Sequencing Fundamental Chemical ConceptsStephen DeMeo It is often confusing for introductory chemistry students to differentiate between molar mass, atomic mass, and mass number as well as to conceptually understand these ideas beyond a surface level. One way to improve understanding is to integrate the concepts, articulate their relationships, and present them in a meaningful sequence. DeMeo, Stephen. J. Chem. Educ.2006, 83, 617.
