Formula of the C1V1 = C2V2 Dilution Calculator

Formula
$$C_1V_1 = C_2V_2$$

Where:

  • $$C1$$ = Concentration of the stock solution
  • $$V1$$ = Volume of the stock solution needed
  • $$C2$$ = Desired concentration of the diluted solution
  • $$V2$$ = Desired volume of the diluted solution

This formula calculates the amount of stock solution (V1) required to reach the desired concentration (C2) and volume (V2).


This equation is commonly used in laboratories for preparing diluted solutions. By knowing the concentration of a stock solution (C1) and the volume of the final diluted solution (V2), you can easily calculate the required volume of stock solution (V1) to achieve the desired concentration (C2).
