what is relative density?
Answers
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. Wikipedia
Formula
RD=\frac{\rho_{\text{substance}}}{\rho_{\text{reference}}}
RD = relative density
\rho_{\text{substance}} = density of the substance being measured
\rho_{\text{ reference}} = Density of the reference
