I am in deperate need of help!!! Physics

The question:
after our sun exhausts its nuclear fuel, its ulitmate fate may be to collapse to a white dwarf state, in which it has approximately the same mass as it has now but a radius equal to the radius of the earth. Calculate: The average density of the white dwarf; the free fall acceleration; the gravitational potential energy associated with a 1.00-kg object on its surface.

I don't even know where to start. I'm lost. PLEASE HELP!!!

Read your class notes and look up the mass of the sun and the radius of the earth.
