Neutron star density. a typical neutron star has a mass of about 1.5m☉ and a radius of 10 kilometers. calculate the average density of a neutron star, in kilograms per cubic centimeter. compare the mass of 1 cm3 of neutron star material to the mass of mount everest ( 5 1010 kg).

(a) One solar mass is equal to , so the mass of the neutron star is 1.5 times this value:


The radius of the star is , so its volume is


So, the density of the neutron star is


(b) We want to find the mass of 1 cm^3 of neutron star. The volume is

so, by using the density we found at point (a), we can calculate the mass of 1 cm^3 of neutron star:


So, 1 cm^3 of neutron star has more mass than Mt Everest (whose mass is ).
