Question

diffrentiate between density and relative density

Answer 1

Answer:

Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

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. ... 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.
