Illustrate the concept of mole through a diagram.

Explanation

Mole:
1) One mode of a substance is the amount of the substance which contains as many particles (atoms, molecules…..etc,) or entities that are equal to the atoms present in exactly 12 grams of `C^12` isotope.
2) The number of particles present in one mode of any substance has a fixed value of `6.022 times 10^23`. This number is called Avagadro'c constant `(N_A)`.
