Dilution Calculator

Formula: C₁V₁ = C₂V₂

Accurately preparing solutions is essential in chemistry, biology, and lab work. Our Dilution Calculator makes it easy to calculate the concentration or volume needed to achieve a desired solution. No more manual calculations or errors—just fast, precise results every time.

Dilution is the process of reducing the concentration of a solute in a solution, usually by adding more solvent. It is commonly used in labs, chemical experiments, medicine, and even in gardening or cooking when working with strong concentrations.

The basic formula for dilution is:C1V1=C2V2C_1 V_1 = C_2 V_2C1​V1​=C2​V2​

Where:

  • C1C_1C1​ = initial concentration
  • V1V_1V1​ = volume of the concentrated solution
  • C2C_2C2​ = final desired concentration
  • V2V_2V2​ = final total volume

How to Use the Dilution Calculator

  1. Enter the initial concentration (C1C_1C1​): Input the concentration of the stock solution.
  2. Enter the desired final concentration (C2C_2C2​): Input the target concentration.
  3. Enter the final volume (V2V_2V2​): Input how much solution you want to prepare.
  4. Click "Calculate": The calculator will instantly compute the volume of stock solution (V1V_1V1​) needed.
  5. View the result: Use the calculated volume to prepare your diluted solution accurately.

This eliminates manual calculations, ensures precision, and saves time in lab experiments or any solution preparation task.


Example: Using the Dilution Calculator

Suppose you have a 10 M stock solution and want to prepare 500 mL of a 2 M solution.

Step 1: Enter C1=10C_1 = 10C1​=10 M, C2=2C_2 = 2C2​=2 M, V2=500V_2 = 500V2​=500 mL.
Step 2: Click “Calculate.”
Step 3: The calculator computes:V1=C2×V2C1=2×50010=100 mLV_1 = \frac{C_2 \times V_2}{C_1} = \frac{2 \times 500}{10} = 100 \text{ mL}V1​=C1​C2​×V2​​=102×500​=100 mL

So, you need 100 mL of the 10 M stock solution, then add 400 mL of solvent to reach 500 mL of a 2 M solution.
