What are the small dense remains of a high mass star
Neutron stars
It can be a black hole or a Neutron Star

Your mass stays the same as if you were on Earth. Your weight will change which is the effect of gravity on your mass. Since the Moon is less dense than the Earth it has a small gravitational pull. This allows you to feel lighter on the Moon. You can jump higher on the Moon and takes longer to fall.

Neutron stars
The bulk of the mass of the atom is concenrated in the small, dense nucleus.
In a way that's what dense means. If something is dense then a small volume of it will have lots of mass. Something that has lots of mass will be subject to considerable gravitational force, which is weight.
The mass remains the same, the star becomes more and more dense as the volume decreases
Dense
the air becomes dense and it sinks
It can be a black hole or a Neutron Star
Having a high mass per unit of volume is what makes a substance dense. Density is defined as the quotient of the mass of a substance and its volume.
Heavy - or - dense
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
