No matter how much of a sample you have, its density is the same. So 1g of lead has the same density as 1,000kg of lead.
To find out which is more dense, just look it up somewhere. Or look at the Periodic Table. Lead's Atomic Mass is much greater than aluminum's, suggesting that it is more dense.
Lead density = 11.34 gram/cubic cmFor 10 cubic cm, mass is 113.4 grams

Numbers greater than 10 include all integers greater than 10, such as 11, 12, 13, and so on. In addition, any decimal or fractional numbers greater than 10, such as 10.1, 10.5, 11.7, etc., are also greater than 10. In mathematical terms, any number that falls to the right of 10 on the number line is considered greater than 10.

We need to calculate the volume of a metal from the density to be sure. Density of pure gold = 19.3  g·cm-3Density of pure lead = 11.34  g·cm-3The volume of 20 g of gold = mass/density = 20 [g] / 19.3  g·cm-3 = 1.036 cm3 The volume of 10 g of lead = mass/density = 10 [g] / 11.34  g·cm-3 = 0.882 cm3 Hence, the volume of 20 g of gold is slightly greater than that of 10 g of lead. =========================
The 10 cm3 of aluminum would have a higher density compared to the 5 cm3 of aluminum. Density is a physical property defined as mass per unit volume, so in this case, the larger volume (10 cm3) would contain more mass, resulting in a higher density compared to the smaller volume (5 cm3).
Density = (mass) / (volume) = 27/10 = 2.7 gm/cm3 .
The density is the mass per unit volume. So, the density = 27/10 = 2.7 grams/cc
Greater in what way? They both have the same mass. Aluminium, being less dense will have a greater volume, but being more abundant will have a smaller value.
The weight is greater for 2 atoms of lead.
Depends on what it is. Like density of 10 grams of flowers would be different than 10 grams of lead. Need more information.
The current density of an aluminum wire can vary depending on its diameter and the specific alloy used. In general, aluminum wires can typically handle current densities ranging from 2-10 A/mm². It is important to consult the manufacturer's specifications or industry standards to determine the appropriate current density for a specific aluminum wire.

The object with the mass of 50g has the greatest density because density is mass divided by volume, and since volume is the same for both objects (since they are the same size), the object with the greater mass will have the greater density.
Uranium is more dense than lead. The reason that it is more dense is because if we compare a given volume of space that uranium takes up and find its weight, it will be greater than the weight of lead that takes up that same volume of space that the uranium did. The uranium is "more closely packed" as regards material in an individual atom and also "more closely packed" on a macro-atomic scale where the atoms are free to form whatever configurations they wish to make in a solid. Both materials are metals, and they both form metallic crystal structures. These two considerations, the "density of the atom" and the "density of a bunch of atoms grouped together" in a solid determine the density of these materials. Note that this is a situation comparing two metals. If we compared the density of lead to the density of, say, radon, we are comparing the density of a metal to the density of a gas. The gas, radon, doesn't have a chance; it is much less dense. But note that the "atomic density" of radon is higher than that of lead. That is, looking at the number of protons and neutrons in a given atom and the volume of space that atom occupies, radon has more weight per unit of volume (a higher density) than lead - at least on an atomic scale (comparing one atom to another). However, radon is an inert gas, and because of this, atoms of radon will not "pack together" like lead atoms will. The atoms of radon want lots of space between themselves, so they disperse, and on a "large scale" the radon is less dense than the lead. And that's the way we generally look at density - on the large scale (as opposed to just one atom). Density is a ratio of the mass of a material per a unit of volume of that material, so the actual masses of the two metals (the 5 kg of Pb and the 10 kg of U) really don't matter. The key in comparing the density of two materials is to compare identical volumes of the materials, and not two amounts of them by weight. In the case of uranium and lead, the uranium weighs 19.1 grams per cubic centimeter, while lead, which we know is pretty "heavy" stuff, weighs 11.34 grams per cubic centimeter. That makes uranium over half again as dense as lead. Just for fun, the density of liquid mercury is 13.534 grams per cubic centimeter. That means lead will float on liquid mercury.
