Detailed explanation-1: -The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.
Detailed explanation-2: -1 mole contains 6.022 x 1023 entities (Avogadro’s number) Concept 1.
Detailed explanation-3: -One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).
Detailed explanation-4: -A mole is defined as the number of atoms in 12 grams of Carbon-12. The number of atoms or molecules in a mole is known as Avogadro’s number, and is equal to 6.022 x 1023. A mole is the SI unit for amount of a pure substance.
Detailed explanation-5: -The MOLE (mol) is a unit of measurement that is the amount of a pure substance containing the same number of chemical units (atoms, molecules etc.) as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 1023).
