The nucleus of the hydrogen atom has a radius of about 12Sol

The nucleus of the hydrogen atom has a radius of about 1.2

Solution

(a) Volume of the atom is Vatom = (4/3)pi(5.29 *10^-11m)^3

Vatom = 6.2*10^-31 m^3

(b) Volume of the nucleus is Vnucleus = (4/3)pi(1.20*10^-15m)^3

Vnucleus = 7.24*10^-45 m^3

c) V2/V1 * 100

[ 7.24*10^-45 / 6.2*10^-31 ] * 100 = 1.167*10^-12
