A. Major Points and Concepts
Types of Chemical Formulas
Empirical Formula: a formula of a compound that expresses the smallest whole-number ratio of the atoms present
Molecular Formula: the actual formula of a compound
Mole
Conversion between Gram and Mole- Molar Mass
Conversion between Atom and Moles- 1 mole = 6.022x10^23 atoms
Conversion between Volume and Mole- 22.4 L=1 mole
1 mole = 6.022x10^23 molecules
