Densities of both nuclei are equal because nuclear density is independent of the mass number of a nuclide.

Two nuclei have mass numbers in the ratio 1: 2. What is the ratio of their nuclear densities?
Share
The ratio of their nuclear densities is 1:1. Nuclear density is nearly constant for all nuclei because it depends only on the nuclear volume and not on the mass number, which scales proportionally with volume.
