Neutron stars are believed to be composed of solid nuclear matter, primarily neutrons. a. If the radius of a neutron is 1.0 x 10^-13 cm, calculate the density of a neutron in g/cm^3. (volume of a sphere=4/3 pi r^3) b. Assuming that a neutron star has the same density as a neutron, calculate the mass in kilograms of a small piece of a neutron star the size of a spherical pebble with a radius of 0.10mm.

## radius is given to you and

radius is given to you and volume = 4/3 pi r^3

use the given radius to find volume and then mass of neutron star to find density

density = mass / volume
