Avogadro’s Large Constant

Many ask why is Avogadro’s is so large. Is there a reason to it?

Well, scientists, especially chemists, say that Avogadro’s number is a constant that helps them in counting the number of atoms in a certain element. This is number is based on the isotope of carbon-12. It is like saying I have one dozen of flowers. The significance of the Avogadro’s number is just mainly to help in determining the number of atoms in a certain molecule.

In the picture, they say that an avogadro grain sand (meaning to say 6.02 x 10^23) is equivalent to height of a  10-storey building.
