Solution Calculations



The concentration of a substance in a solution or mixture can be expressed in a number of ways. Four of the most common are defined below:


Molarity (M) = moles of solute / liters of solution Percent weight (%(w/w)) = 100 x (mass of solute / mass of solution) Percent volume-volume (%(v/v)) = 100 x (volume of solute / volume of solution) Percent weight-volume (%(w/v)) = 100 x (g of solute / ml of solution)
