Answer 2

Mole is the unit of amount of substance. It is defined as the amount of substance that contains as many particles as there are atoms in exactly   12 g $C^{12}$ isotope. 1 mole of any substance contains $6.022 \times10 ^{23}$ atoms. This number is known as Avogadro number or Avogadro constant.

1 mol of hydrogen atoms = $6.022 \times10 ^{23}$ atoms

1 mol of water molecules = $6.022 \times10 ^{23}$ water molecules

1 mol of sodium chloride = $6.022 \times10 ^{23}$ formula units of sodium chloride
