In chemistry, the mass concentration ρi (or γi) is defined as the mass of a constituent mi divided by the volume of the mixture V. 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. (Wikipedia).

Expressing Concentration by Mass Percent
We know how to express solution concentration in terms of molarity and molality, but the common public also needs to communicate concentration for certain reasons, and they don't really know about moles and things like that. What do they use? Mass percent! Watch the whole General Chemistr
