The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.
The density of the iron piece is calculated by dividing the mass by the volume. In this case, the density would be 2kg / 256 cm^3 = 0.0078 kg/cm^3.
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 = 57.2g/11 cm3 = 5.2 gcm-3
The volume is 0,62 L or 6,2 dL.
-- 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.
Of course not...different densities, different volumes per same weight.
Density = Mass/Volume = 5.6grams/20cm2 = 0.28 g/cm3 This is clearly a hollow piece of iron since the density of solid iron is 7.9 g/cm3
No, copper does not have more volume than iron for the same weight or mass. Copper is denser than iron, so a given mass of copper will have a smaller volume than the same mass of iron.
Specific gravity of iron is approximately 7.85 3.2 kg divided by 7.85 = 0.4076 litre or 407.6 millilitres
The density is 7.8 grams per cm^3.
Density = Mass/Volume D = 48/6 = 8 g/cm^3
