The eight lessons in this unit cover atomic and molecular weights, the mole concept, and its applications to stoichiometric calculations involving formulas and equations. A considerable number of problems are included. It is the author's experience that many students who experience difficulty with these topics can benefit from a more detailed treatment of topics that are often passed over in conventional instruction; examples are net ionic equations, and recognizing decimal equivalents of integer ratios, which is important in understanding "simplest formula" calculations.
Note: this lesson set is included with the Chem1 Starter Set; there is no need to download it separately.
Each bulleted item is individually accessible through a 2-level menu.
