If you weigh 660 on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 21.0 ?

If you weigh 660 on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 21.0 ? Take the mass of the sun to be = 1.99×1030 , the gravitational constant to be = 6.67×10−11 , and the acceleration due to gravity at the earth's surface to be = 9.810 .
