A neutron star whose mass is k6i6lx/0 tif w1.5 solar massesr7 0s;j cyhl3-i8 ijfa has a radius of about 11 km. Calcua0 hy3ijcj-; l 8rfs7ilate its average density and compare to that for a white dwarf (Problem 13) and to that of nuclear matter.
$\rho_{\text{neutron star}} \approx $ $\times 10^{17}\ \text{kg/m}^3$
$\dfrac{\rho_{\text{neutron star}}}{\rho_{\text{white dwarf}}} =$ $\times 10^8$
$\dfrac{\rho_{\text{neutron star}}}{\rho_{\text{nuclear matter}}}$ =
