Avogadro number calculator computes how many units of something are present in one mole of that substance.

It uses the basic formula to calculate the result. The equation includes volume, density, atomic mass of the substance, and atomic number (Z).

Avogadro’s number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance.

Its value is 6.022 x 1023 units in each mole. Its symbol is NA.

• One mole of water has Avogadro’s number of molecules.
• One mole of atomic oxygen has 6.022 x 1023 oxygen atoms.
• One mole of CO2 contains Avogadro’s number of carbon atoms.

Avogadro number is a fixed amount of units in a mole. The unit of Avogadro’s number can be found through the following formula:

No. of atoms = Avogadro’s number × moles
