Oh, blondie.
"Mass" will be the same. Relative displacement, NOT.

Mass is the fundamental measure of the matter of an object.
Weight is the mass of an object times the force of gravity acting upon it.
Mass typically refers to inertial mass which means how much the object resists movement, or the amount of matter without an acceleration force (gravity) acting on it.
Mass is the volume of the object times its density. It does not change under gravity. so in your example a 1 kg mass of feathers and a 1 kg mass of iron would weigh the same under the same gravity, however the mass of feathers would take up more volume than the iron because it is less dense.

A kilogram of iron of course! ;-)

A kilogram is a kilogram is a kilogram.
