What is mole: Mole concept is known as

Mole concept is known as the method used to express the amount of substance. A mole is defined as the amount of substance containing the same number of different entities (such as atoms, ions, and molecules) as the number of atoms in a sample of pure 12C weighing precisely 12 g. Learn what a mole is and how to calculate the number of moles, molar mass, and related quantities of a substance. A mole is the amount of a substance that contains exactly 6.02214076 " 1023 elementary entities. Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. As of 2019, the mole is defined more precisely: One mole contains exactly 6.02214076 × 10²³ elementary entities. It is no longer tied to the mass of carbon-12.
