| To Calculate the Radius of Atom by Making Use of Avogadro's Hypothesis |
|
| By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3rd of the volume occupied by 1 gram of the substance. |
| |
| Let us consider a sample of a substance of mass m and volume V. If M is its molecular weight and Avogadro number is N, then |

| Where r = radius of each atom. |

| By Avogadro's hypothesis, |
