Question

The question:
If the radius of a neutron is 1.0 x 10 ^ -13 cm calculate its density in g/cm^3
volume= 4/3(pi)r^3

I have the volume already but we weren't given the mass of the neutron.

Answer 1

Answer:

Neutron stars are composed of solid nuclear matter, primarily neutrons. Assume the radius of a neutron is approximately 1.0×10−131.0×10

−13

cm. Calculate the density of a neutron. [Hint: For a sph ere V = (4/3)πr3πr

3

.] Assuming that a neutron star has the same density as a neutron, calculate the mass (in kg) of a small piece of a neutron star the size of a spherical pebble with a radius of 0.10 mm.
