Detailed explanation-1: -A mole (mol) is the amount of a substance that contains 6.02×1023 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02×1023 water molecules in a mole of water molecules.
Detailed explanation-2: -One mole of any substance contains 6.022×1023 atoms/molecules.
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: -One mole of a substance contains 6.022×1023 particles.
Detailed explanation-5: -A mole (mol) of a substance is 6.02 × 1023 representative particles of that substance and is the SI unit for measuring the amount of a substance. The number of representative particles in a mole, 6.02 × 1023, is called Avogadro’s number.
