Question:
The radius of an atom is of the order of 1 Å and radius of nucleus is of the order of fermi. How many magnitudes higher is the volume of the atom as compared to
the volume of the nucleus?
Solution:
Radius of atom = 1 Å = 10-10 m
Radius of nucleus = 1 fermi = 10-15 m
Volume of atom = 4/3πRa3
Volume of nucleus = 4/3πRn3
Vatom/Vnucleus = 1015
Mass of one mole of carbon atom = 12 g = 1.67 × 10-27 kg
