Question

relative density is very important in the accurate determination of density --- explain.

Answer 1

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage. It is defined as a ratio of density of particular substance with that of water.

If a substance's relative density is less than one then it is less dense than the reference; if greater than 1 then it is denser than the reference. If the relative density is exactly 1 then the densities are equal; that is, equal volumes of the two substances have the same mass. If the reference material is water then a substance with a relative density (or specific gravity) less than 1 will float in water. For example, an ice cube, with a relative density of about 0.91, will float. A substance with a relative density greater than 1 will sink

Héllō Buddy!!

•The answer Is ==> Relative density tells us how heavy the substance is in comparison to water.It helps us to determine the density ofan unknown substance by knowing thedensity of a known substance.It is very important in the accurate determination of density.
