How many moles are in an atom?

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms molecules or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant.

How many moles of atoms are there in one atom?

Thus there are 6.022×1023atoms in exactly one mole of atom. Note: Note that the Avogadro number also relates the molar volume of a substance to that of the average volume which is nominally occupied by one of its particles when both are expressed in the same units of volume.
