One kilogram. Mass is invariant.
The weight at that point is zero. But the mass doesn't change.
Yes.
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.

No, scientists have not yet drilled into the Earth's lower mantle. This region of the Earth is located about 400 to 1,800 miles below the surface, making it extremely difficult to reach with current drilling technology. The deepest hole ever drilled, the Kola Superdeep Borehole in Russia, only reached about 7.5 miles deep.
