Consider a neutron star of mass M = 1.99e+030 kg and a radius of R = 9 km.

Assuming uniform density, how much would 1.1 cubic centimeters of neutron star material weigh on the surface of the earth?

2. Relevant equations

Volume of Sphere = (4/3)pi(r^3)

density = Mass/Volume

gravity = 9.81 m/s^2

First I converted 9km to 9000m, and 1.1cm^3 to .011m^3

solve for density; (M=1.99e30)/(vol=(4/3)pi(9000^3) = 6.5168e17

(.011 x 6.5168e17) x 9.81 = 7.0323e16 N

its not accepting my answer
