Density = Mass/Volume = 57.2g/11 cm3 = 5.2 gcm-3
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
10.5 g cm-3
Volume cannot be 29.4 cm since that is a measure of a length, not volume. Assuming that you meant 29.4 cm3, the density is mass/volume = 25.0 g / 29.4 cm3 = 0.850 grams per cubic centimetre (to 3 dp).
Density = mass/volume = 75g/1500 cm3 = 1/200 g/cm3 = 0.050 g/cm3That value is half of common balsa wood density (there are other woods that are less dense but your example is rater extreme)
Since density is defined as mass divided by volume, the statement that the 100g piece of iron has twice the density as the 50g piece would only be true if they occupied the same volume. However, since iron is an element, it will not vary so widely in density in solid form. Thus, it is more than likely that they are different volumes with the same density, and only the mass of the first piece is twice the mass of the second.
Iron pyrite (FeS2) has a density of 4.8 to 5.0 grams per cm3. A piece of volume 40 cm3 would, therefore have a mass of volume*density = 192 to 200 grams.
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
10.5 g cm-3
its has higher density
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.

you can get the volume by using the density formula, since density of silver is a constant and given thing. density= mass/volume volume=mass/density.
Divide mass by volume to get density
The density of silver is 10490 kg/m3. You need to have a piece of silver for it to have a mass or volume.
Density = Mass/Volume = 25.0/28.7 = 0.871 units of mass per units of volume.
