What is meant by relative density and it's formula?
Verified Answer
What is meant by relative density and it's formula?
The relative density of a substance is defined as the ratio of the density of that substance to the density of water at 4degreeC. It is also defined as the ratio of the mass of substance to the mass of equal volume of water at 4degreeC. i.e., R.D. = Mass of the substance / mass of an equal volume of water at 4degreeC.
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.
