More Information
One mole of any substance contains Avogadro's number, which is 6.022 x 10²³, a constant used to quantify atoms, molecules, ions, or other elementary entities.
Tips
A common mistake is to forget that a mole refers to 6.022 x 10²³ elementary entities and not to a specific mass or physical size.
