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
No, both a kilogram of feathers and a kilogram of lead would weigh the same, as they both have a mass of one kilogram. However, the volume of feathers would be much larger than the volume of lead due to their different densities.

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.

One kilogram of lead is denser than one kilogram of feathers, so it takes up less space. This makes it easier to carry the lead compared to the same weight of feathers, which would occupy much more volume and be more cumbersome.
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.
A kilogram of lead weighs the same as a kilogram of feathers. The difference lies in the volume and density of the materials - lead being much denser than feathers, so it would take up much less space than the feathers.
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.
A pound of lead weighs the same as a pound of feathers. The weight is the same, but the volume of feathers will be much greater than that of lead.
