No. Density is equal to mass over volume. It has nothing to do with the weight.

∙ 13y agoYes, a pound of cotton and a pound of lead have the same density because density is a property of a material that is independent of its weight. Density is defined as mass per unit volume, so if both the cotton and lead weigh the same, they should have the same density.
A pound of gold weighs the same as a pound of cotton. The difference lies in the density and volume of the two materials. Gold is denser and takes up less space, making it more valuable by weight compared to cotton.
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.
Density is mass divided by volume. If we assume the mass of the iron and the cotton is the same, you will find that the iron will occupy less space (less volume) than that of the cotton. The value of a mass divided by a small volume is higher than the value of the same mass divided by a larger volume. If we assume the volume of both the iron and the cotton is the same, you will also find that the mass of the iron will be higher than the mass of the cotton. The value of a large mass divided by a volume is larger than the value of a small mass divided by the same volume. In both assumptions, the value of mass divided by volume for the iron is higher than the value of mass divided by volume for the cotton. Since density is mass divided by volume, the density of iron is therefore higher than the density of cotton.
Neither of those items weighs more. We know that, because you have told us the weightof each item, and we have completed a comparative calculation. One of them weighsone pound and the other weighs one pound. One pound is equal to one pound. So theweight of one is equal to the weight of the other, and neither of them weighs more thanthe other. Reasoning symmetrically, we are also mathematically entitled to state thatneither of them weighs less than the other one either, as well, also, too.
The same as the density of 1 kilogram, or 1/10 kilogram, or whatever. Density is not a property that depends on the amount of a substance.
One pound of stone is heavier than one pound of cotton. While they both weigh the same amount, the density of stone is higher than cotton, so a pound of stone takes up less space and feels heavier.
Steel is heavier than lead. Lead is a dense metal with a density of 11,340 kg/m³, while steel has a density ranging from 7,750 kg/m³ to 8,050 kg/m³. This means that a given volume of steel will weigh more than the same volume of lead.
They both are the same
A pound of gold weighs the same as a pound of cotton. The difference lies in the density and volume of the two materials. Gold is denser and takes up less space, making it more valuable by weight compared to cotton.
Same. That's an old trick question but feathers were more commonly used than cotton.
A pound of any substance, material or "stuff" weighs the same as a pound of anything else. A pound is a pound, whether it's cotton or nails.
A pound of gold and a pound of cotton weigh the same because they both weigh one pound. The difference lies in their volume and value, as gold is much denser and more valuable than cotton.
Both a pound of cotton soak and wet and a pound of stone weigh the same - one pound. Weight is not determined by the material, but by the mass.
they both weigh the same because a pound of sand and a pound of lead will still weigh a pound
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.
Density is mass divided by volume. If we assume the mass of the iron and the cotton is the same, you will find that the iron will occupy less space (less volume) than that of the cotton. The value of a mass divided by a small volume is higher than the value of the same mass divided by a larger volume. If we assume the volume of both the iron and the cotton is the same, you will also find that the mass of the iron will be higher than the mass of the cotton. The value of a large mass divided by a volume is larger than the value of a small mass divided by the same volume. In both assumptions, the value of mass divided by volume for the iron is higher than the value of mass divided by volume for the cotton. Since density is mass divided by volume, the density of iron is therefore higher than the density of cotton.
