## 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 M_{1}V_{1} = M_{2}V_{2} 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.
