HOW THE AVOGADRO NUMBER HELPS WORK OUT SCALES?

An Italian scientist Amedeo Avogadro, in the year 1811, suggested that at a particular pressure or temperature, the volume of gas is proportional to the number of moles or molecules present on the gas irrespective of the nature of gas. To honor and glorify it, a French scientist, Jean Perrin, proposed to name this constant in the name of Avogadro. This happened in 1909. Later on, he won a Nobel Prize in Physics in the year of 1926, for figuring out the exact value of Avogadro number.
