Question

what do you mean by relative density? What does it tell you?​

Answer 1

Explanation:

relative density = density of material divided by density of water.

it tells whether the material is heavier or lighter than water

Answer 2

Answer :

Relative density , or specific gravity , is the ratio of the density ( mass of a unit volume ) of the substance to the density of a given reference material .

If a substances relative density is less than 1 then it is less dense than the reference , if greater than 1 then it is more denser than reference.
