There is relatively little empty space between atoms in solids and liquids, so that the average density of an atom is about the same as matter on a macroscopic scale-approximately 103 kg/m³. The nucleus of an atom has a radius about 10-5 that of the atom and contains nearly all the mass of the entire atom. (a) What is the approximate density (in kg/m³) of a nucleus? 1000000000000 x in kg/m³ (b) One remnant of a supernova, called a neutron star, can have the density of a nucleus. What would be the radius (in m) of a neutron star with a mass 1.3 times that of our Sun (the radius of the Sun is 7 x 108 m)? ✔m 8510
