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?

Radius of atom is given as 1 Å = 10^{-10} m

Radius of nucleus is known as 1 fermi = 10^{-15} m

Volume of atom will be 4/3\pi Ra^{3}

Volume of nucleus will be 4/3\pi Rn^{3}

\frac{V_{atom}}{V_{nucleus}}=10^{15}

Mass of one mole of carbon atom is 12g=1.67\times 10^{-27}kg
