The density of a material is defined as its mass per unit volume. A given volume of lead has more mass than a given volume of feathers. In common usage mass often refers to weight, but that is not a very exact usage of it. For this question it may be useful however to think of a given weight of lead per volume and a given weight of feathers.If you have a kg of lead, that is a small piece, a kg of feathers is a large amount.So for a given volume, say a cubic centimeter, the weight of lead is much more than the weight of feathers.
They both weight a kilogram. Lead has a higher density.
Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
Lead
the same
They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
Butter has greater volume than lead because butter has more mass.

A kilogram is a measure of mass therefore a kilogram of lead and a kilogram of feathers have the same mass: one kilogram. They would, however, have different volumes and densities.
No, both weigh a kilogram
They both weight a kilogram. Lead has a higher density.
The feathers "take up more room" than the lead. It would be hard to compress the feathers to make them as dense as lead. The feathers have more volume.
Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
Lead
That depends on the substance that the kilogram is made of. A kilogram of air has a large volume. A kilogram of water has a medium volume. A kilogram of lead or stones has a small volume.
