-- 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.

Density = Mass/Volume = 25g / 4 cm3 = 6.25 g/cm3

Given that the volume=95.7cm3 ,density=9.3gcm3, mass=? .But density=mass per unit volume.hence mass=density times volume, substituting for density and volume, mass=95.7 times 9.3=890.01g

That would vary greatly depending on the type and density of the metal, along with the dimensions of the particular piece. The weight of a piece of anything is the volume times the density.

The density is the ratio of mass to volume. It doesn't matter what size the piece of metal, if it is the same metal it has the same density, 8.4.

10.5 g cm-3

Density = Mass/Volume = 57.2g/11 cm3 = 5.2 gcm-3

Volume = mass/volume = 500g/10cm3 = 50g/cm3

Density= mass/volume 25/10 = 2.5 g/cm3

To find density, the formula is 750 (grams) divided by 55 (cubed cm). 13.64 grams/cm^3, or 14 grams/cm^3 in 2 significant figures.

Density = Mass/Volume so Volume = Mass/Density. That is, Vol = 1.5 g/2.3 g/ml = 0.652 ml approx.
