It is the number of molecules in one mole of a substance in one mole (mass/atomic mass). It is equal to 6.0221415 × 10^23 about. Most commonly just rounded to 6.02x10^23

Avogadro's number is the set constant number of atoms in a mole of a substance, and is set at 6.0221415*10^23

Avogadro's Number
= 6.023 x 10^23
This many things equals 1 mole of things (no matter what)
atoms, molecules, farts, busses, anything.
Just like 12 = 1 dozen or 144 = 1 gross
6.023 x 10^23 = 1 mole

6.0221415 Ã 10^23
The Avogadro constant can be applied to any substance. It corresponds to the number of atoms or molecules needed to make up a mass equal to the substance's atomic or molecular mass, in grams.

Avogadro's number=6.022 x 10to the power of 23
Signifcance- this is the no. of atoms in one mole of an element. so 1mole of oxygen has the same no. of atoms as Chlorine.
Note well, i never said the same mass. even though they both have the same no. of atoms, the mass of one atom of oxygen is different from the mass of one atom of chlorine thus all elemnts have different atomic mass numbers.
