What is Avogadro's Number?
The number of particles in 1 mole of any substance. 1mol of anything = 6.02x1023. It can be used as a conversion factor from atoms to moles or moles to atoms.
Avogadro's Number = 6.022x1023
There are 6.022x1023 atoms in 1 mole of atoms. Therefore, we can use these conversion factors:
[ 6.022x1023 atoms / 1 mole of atoms ] and [ 1 mole of atoms / 6.022x1023 atoms ] Eg: mole: The number of Carbon-12 atoms in 0.012 kg of Carbon-12
NA = 6.02214129(27)x 1023 mol-1
Formula:
N = (Z × M) / (D × V)
where,D = Density,
M = Average atomic mass,
V = Volume,
Z = Number of atoms within the crystal unit cell
