Specific gravity refers to the ratio of the density of a substance to the density of a standard, which is usually water. A piece of metal that has a mass of 200 g and a volume of 2 cm3 has a specific gravity of 100.
The object has a mass of 0.5 g/cm3
100g/cm3 this is 5 times denser than the densest element
Just divide the mass by the volume.
5g/cm3
-- 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.
19.3. Specific gravity is another way of saying density.
The piece of wood floats in water because its specific gravity is less than water.
20cm3
5g/cm3
-- 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.
Specific gravity of iron is approximately 7.85 3.2 kg divided by 7.85 = 0.4076 litre or 407.6 millilitres
Volume = mass/volume = 500g/10cm3 = 50g/cm3
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 piece of wood floats in water because its specific gravity is less than water.
A piece of aluminum foil has a fixed mass and volume, it is flexible, and it is a metal that can conduct electricity.
Place the piece of metal in 50mL of water and subtract the 50mL from the new volume of water. The difference will be the volume of the metal in mL and cm3. Then find the density by dividing the mass by the volume of the metal. The water must completely cover the metal in order for the displacement method of determining the volume to work.
It is not used for this.A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids, NOT rock.To measure the density of a rock you weigh a piece of it in air, then measure the volume of water it displaces in a measuring jug.Density = mass/volume.

The reading on the graduated scale is taken before and after the metal is lowered into the cylinder . The second reading is subtracted from the first. This gives the volume of the metal in cubic centimetres.
