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.

How many times is 300 greater than 30?
ten
Is 0 greater or less than -10?
10
Is 01 greater than 10?
No, 01 (which is one) is not greater than 10. And .01 is not greater than 10, either.
Which number is greater .1 or .8?
.8 is greater than .1 or 8/10 is greater than 1/10
Is the volume of gold 20g greater than the volume of lead 10g?
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. =========================
What is the density of a block of aluminum that has mass 27 grams of and a volume 10 cubic cm?
The density is the mass per unit volume. So, the density = 27/10 = 2.7 grams/cc
What is the density of 10 grams and 5ml?
Depends on what it is. Like density of 10 grams of flowers would be different than 10 grams of lead. Need more information.
What has a greater mass 2 atoms of lead or 5.1 X 10-23 mole of helium?
The weight is greater for 2 atoms of lead.
What is greater 10 gram of aluminum or 10 gram of iron?
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.
What is the density of 6005 aluminum?
Physical Data : [top] Density (lb / cu. in.) 0.098 Specific Gravity 2.7 Melting Point (Deg F) 1090 Modulus of Elasticity Tension 10 Modulus of Elasticity Torsion 3.8
What is the density of a block of aluminum that has a mass of twenty seven grams and a volume of ten centimeters to the third power?
Density = (mass) / (volume) = 27/10 = 2.7 gm/cm3 .
What is the mass of a 10.0 cu centimeters of lead?
Lead density = 11.34 gram/cubic cmFor 10 cubic cm, mass is 113.4 grams
Which one is more dense carbon or aluminum?
I am assuming you mean the atoms of these two elements. We can do the simple math and find out: density = mass/volume atomic mass of carbon = 12.01 amu = 1.99 x 10-23 grams atomic mass of aluminum = 26.98 amu = 4.48 x 10-23 grams volume of a sphere (atom) = 4/3 x pi x r3 atomic radius of carbon = 70 pm = 7.0 x 10-9 cm atomic radius of aluminum = 125 pm = 1.25 x 10-8 cm density (carbon) = 13.85 g/cm3 density (aluminum) = 5.48 g/cm3 Carbon is more dense.
Which has the greater density 5 kg silver or 10 kg steel?
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.
Can you tell difference between aluminum and lead?
At first glance they might be hard to distinguish, but on closer inspection you'll notice that lead is much heavier than aluminum. The density of those metals are 11.34 g\cm3 for lead and 2.7 g\cm3 for aluminum. In other words a cubic centimeter of lead weights 11.34 grams, while a cub. centimeter of aluminum only 2.7 grams. Aluminum is also harder than lead. Aluminum scores 2.75 in Mohs' hardness test, while lead scores only 1.5 (Graphite scores 1, Diamond scores 10). If you're still not sure you can try and melt both metals. The melting point for aluminum is 660.32 deg. Celsius (1220.50* F) while for lead it is only 327.46 deg. Celsius (621.43* F). In other words lead will melt in lower temperatures than aluminum. There are a lot of other differences but the ones i quoted are quite easy to verify using simple methods (scales, sharp nail and a gas cooker respectively). Also, if you happen to have a strong magnet at hand you can check their magnetic ordering. Aluminum is "paramagnetic" which means it is attracted by magnetic fields. Lead is "diamagnetic" - applying a magnetic field will not attract it (to be more precise, it will cause a repulsive effect but a very, very weak one - it cannot be observed in normal circumstances).
a scientist has a sample of a substance with a volume of 50cm cubed and a mass of 135g. this is most likely a sample og which substance gold, pure water, aluminum or ocean water?
The **density** of a substance is defined as its mass per unit volume. We can calculate the density using the formula: [ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} ] Given that the sample has a volume of **50 cm³** and a mass of **135 g**, let's determine the density: [ \rho = \frac{135 , \text{g}}{50 , \text{cm³}} ] The calculated density is approximately **2.7 g/cm³**[^10^]. Now let's compare this value to known densities: **Gold**: Gold has a density of *19.3 g/cm³*⁷. The sample's density is significantly lower. **Pure Water**: The density of pure water is approximately **1 g/cm³** at 4.0°C (39.2°F) . The sample's density is higher than water. **Aluminum**: Aluminum has a density of *2.7 g/cm³*[^10^]. The sample's density matches that of aluminum. **Ocean Water**: Ocean water contains dissolved salts, which increase its density. Seawater density typically ranges from *1.02 g/cm³ to 1.03 g/cm³*. The sample's density is higher than seawater. Based on the calculated density, the sample is most likely **aluminum**.
