The concept of what the mole is and how the units of atomic mass unit (amu) and grams are related through the Avogadro number are explored. Classification of matter is also discussed regarding the distinction between atoms and molecules.

The concept of mole ratios between the atoms in a molecule and the mole ratios between different compounds in a chemical reaction (and thus balanced chemical equations) are explored. This concept then leads into stoichiometry calculations.

Different types of mole calculations are explored using the conversion factors of molar mass, concentration, and volume of a gas. An emphasis is placed on correctly setting up the calculations so that units cancel out.
