Molarity (molar concentration) To find the molarity of a solution, divide the number of moles of solute (dissolved substance) by the total volume of the solution: Dilution of solutions. If solution of molarity M1 and volume V1 is diluted to molarity M2 and volume V2, the following relation can be used: Use this formula only for dilution of ...

Molality is the number of moles of solute per kilogram of solvent. Molality is used when: (1) the solute interacts with the solute, (2) when making a very concentrated solution, (3) when the solution involves a solvent other than water, or (4) when the solution undergoes a temperature change that alters the density of the solvent.
