Answer:
Key Points
The mole allows scientists to calculate the number of elementary entities (usually atoms or molecules) in a certain mass of a given substance.
Avogadro’s number is an absolute number: there are 6.022×1023 elementary entities in 1 mole. This can also be written as 6.022×1023 mol-1.
The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
Term
moleThe amount of substance of a system that contains as many elementary entities as there are atoms in 12 g of carbon-12.

Answer:
The number of atoms or molecules in one mole of a substance, equal to 6.023 × 1023 is called avagadro's constant.
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'sconstant. The concept of the mole can be used to convert between mass and number of particles.
