Mass concentration (chemistry)
In chemistry, the mass concentration (or
) is defined as the mass of a constituent
divided by the volume of the mixture s
:
For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture. This explains the usage of ρ (the lower case Greek letter rho), the symbol most often used for density.
