Meaning
The Avogadro Constant is the number of atoms in 12g of Carbon. 6.02x1023 atoms per mole.
About the Avogadro Constant
- The Avogadro Constant is used to state the number of atoms or molecules in a mole of a substance.
- The Avogadro 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.
