Understanding Solution Concentration (Mass/Volume)
Mass concentration (ρi or γi) of a solution is defined as the mass of a constituent (mi) divided by the volume of the mixture (V). It is a common way to express the composition of solutions in chemistry and other fields.
Formula: Concentration (ρi) = Mass of solute (mi) / Volume of solution (V)
The SI unit for mass concentration is kilograms per cubic meter (kg/m³). Other common units include grams per liter (g/L) and pounds per gallon (lb/gal).
