Mass concentration (chemistry)

In chemistry, the mass concentration \rho_i (or \gamma_i) is defined as the mass of a constituent m_i divided by the volume of the mixture sV:

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.
