Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions
