About the Avagadro Constant
- The Avagadro Constant is used to state the number of atoms or molecules in a mole of a substance.
- The Avagadro Constant is normally written in Standard Form.
- 6.02x1023 = 602,000,000,000,000,000,000,000 correct to 3 Significant Figures.
- 1 mole of an element contains 6.02x1023 atoms of that element.
- 1 mole of a molecule contains 6.02x1023 molecules.
