Solution Dilution Calculator

Dilute Solution of Known Molarity

The solution dilution calculator tool calculates the volume of stock concentrate to add to achieve a specified volume and concentration. The calculator uses the formula M1V1 = M2V2 where "1" represents the concentrated conditions (i.e. stock solution Molarity and volume) and "2" represents the diluted conditions (i.e. desired volume and Molarity). To prepare a solution of specific Molarity based on mass, please use the Mass Molarity Calculator. To dilute a solution of concentrated acid or base of known w/w% strength, please use the Acid & Base Molarity Calculator.
