1. Determine the approximate radius of the nucleus of a cobalt atom. Cobalt has 27 protons and 32 neutrons.

2. If the atomic mass of cobolt is 58.93u determine the density of the cobalt nucleus in kg/m^3

3. Compare this to the density of cobalt metal (use google). How does the density of cobalt metal compare to the density of just its nucleus? If they do not match please explain why they do not match.
