WebThe density of the nucleus of an atom is, on average, about 2.3×1017 kg/m3. This is called nuclear density. It is the same for all the nuclei, as it does not depend upon the mass number or the size of the nucleus. ρ = mass of nucleus / volume of nucleus ⇒ ρ = 3m / 4π R3o where, m = average mass of a nucleon.
