A neutron star whose mass is ,a0)2xj5f9ue sq hgun 1.5 solar masses has a radius ofv-3e kdi +1/t+rreyag+ lq hh( about 11 km. Calculate its average density and compare to that for a whiteit/ hrlr1q(h- vk+egd3+ya + e dwarf (Problem 13) and to that of nuclear matter.
$\rho_{\text{neutron star}} \approx $ $\times 10^{17}\ \text{kg/m}^3$
$\dfrac{\rho_{\text{neutron star}}}{\rho_{\text{white dwarf}}} =$ $\times 10^8$
$\dfrac{\rho_{\text{neutron star}}}{\rho_{\text{nuclear matter}}}$ =
