The number of units in one mole of any substance is known as Avogadro’s constant or Avogadro number. The units may be ions, electrons, atoms, or molecules, based on the character of the reaction and the product type. The symbol NA represents avogadro’s number.
NA = 6.022 x 1023.
- Avogadro’s number is fundamental to understanding both the makeup of molecules and their interactions and combinations.
- Another property of Avogadro’s number is that the mass of one mole of a substance is equal to that substance’s molecular weight.
