Dilution Calculator
Use C1V1 = C2V2 to calculate the stock solution volume and solvent volume needed for a target dilution.
What This Tool Does
Use C1V1 = C2V2 to calculate the stock solution volume and solvent volume needed for a target dilution.
C1V1 = C2V2
Worked Example
Starting from 1.0 M stock to make 100 mL of 0.10 M solution requires 10 mL stock and 90 mL solvent.
Common Mistakes
Dilution only works when the target concentration is lower than the stock concentration.
