Question

what is relative density?​

Answer 1

Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest; for gases, the reference is air at room temperature.

HOPE THAT THIS HELPS YOU.

Answer 2

Answer:

ok

thank you

Explanation:

Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest; for gases, the reference is air at room temperature.

RD = rhosubstance / rhoreference

RD = relative density

rhosubstance= density of the substance being measured

rhoreference= Density of the reference
