# Avogadro Number Calculator

Posted by Dinesh onCalculate number of molecules in a mole of a substance using

**avogadro constant**calculator online.

### What is Avogadro's Number?

The number of particles in 1 mole of any substance. 1mol of anything = 6.02x10^{23}. It can be used as a conversion factor from atoms to moles or moles to atoms.

Avogadro's Number = 6.022x10^{23}

There are 6.022x10^{23} atoms in 1 mole of atoms. Therefore, we can use these conversion factors:

`[ 6.022x10`^{23} atoms / 1 mole of atoms ] and [ 1 mole of atoms / 6.022x10^{23} atoms ]

Eg: mole: The number of Carbon-12 atoms in 0.012 kg of Carbon-12

N_{A} = 6.02214129(27)x 10^{23} mol^{-1}

## Avogadro Number Calculation

### Formula:

N = (Z × M) / (D × V)

where,D = Density,

M = Average atomic mass,

V = Volume,

Z = Number of atoms within the crystal unit cell
