A neutron star whose h8s:m jk/5fhns36 azpmass is 1.5 solar masses has a radius of abxw*: 6u cl9cz2r2co afout 11 km. Calculate its average density and compare to that for a white dwarf (Problem 13) and to that of nuclear m c* fcz2lxoac2u:rw69atter.
$\rho_{\text{neutron star}} \approx $ $\times 10^{17}\ \text{kg/m}^3$
$\dfrac{\rho_{\text{neutron star}}}{\rho_{\text{white dwarf}}} =$ $\times 10^8$
$\dfrac{\rho_{\text{neutron star}}}{\rho_{\text{nuclear matter}}}$ =
