Molar Density

Molar density is a measure of the number of moles of a substance per unit volume.  It is often used in chemistry and physics to describe how densely packed the molecules (or moles) of a substance are within a given volume.  Molar density is used for understanding concentrations in chemical reactions and processes like gas behavior under different conditions.

 

Molar Density Formula
\( \rho_m \;=\;  n \;/\; V  \)     (Molar Density) \( n \;=\;  \rho_m \; V  \) \( V \;=\;  n \;/\; \rho_m  \)
Symbol	English	Metric
\( \rho_m \)   (Greek symbol rho) = Molar Density	-	\(mol\;/\;L\)
\( n \) = Number of Moles	-	\(mol\)
\( V \) = Substance Volume	-	\(L\)
