lead is much more dense than feathers, so 1 kg of lead occupies much less space (volume) than 1 kg of feathers
It might read something like this: In the universe, we can look around and discover that there is a lot of matter in it. And when we look at matter, we can say that it is anything that has mass and occupies a volume of space. Considering that matter has the property of mass, and that the mass of this matter is taking up a volume of space, we can make a statement about how much mass the matter has per a unit volume of space that it occupies. Mass per unit of volume is what density is. Density is a measure of how "tightly packed together" matter is. As an example, a block of pine wood floats on liquid water, but a chunk of lead sinks to the bottom. Pine is less dense than water, and lead is more dense than that water.
no
That depends on the amounts, of course - what exactly you are comparing. The buoyant force depends on the volume. For a certain volume of lead, there will be the same buoyant force as for the same volume of iron. On the other hand, since lead has a greater density, the buoyant force on a certain amount of MASS of lead will be less, compared to iron, since the same mass of lead will use up less volume.
100 grams of water takes up more space than an equal weight of lead. That is why lead does not float in water.
aluminium
Magnesium-Aluminum Alloy
Any material has a density which is derived from its mass or weight divided by its volume. Lead for example is more dense than aluminum, so a Kilogramme of lead would displace less water than a Kilogramme of aluminum.

The density is 10.7 g/mL. The sample is not pure lead because the density of pure lead is 11.3 g/mL.
Lead will always have the greater density compared to aluminium. The weight only influences the volume in question. 10kg of Al will be much more(bigger in size) than 5kg of lead.

separate mixtures into their componets lead and aluminum pellets
Lead
no because the molar mass of lead is great than aluminum
There is no Lead (Pb) in Aluminum (Al), since Al is a pure, metallic element by itself.
