Dilution Setup
Pick what to solve for and enter values
Solve for
C₁V₁ = C₂V₂. Leave the unknown field empty. Example: C₁=2M, C₂=0.5M, V₂=500mL → V₁=125mL.
Result
Enter values to see result
Enter values to see the dilution calculation.
C₁V₁ = C₂V₂ ensures moles of solute remain constant before and after dilution. Only water is added, not solute.
How to Use
- Select what to solve for :- Choose V₁, C₁, C₂, or V₂
- Enter known values :- Fill in the three known quantities (leave the unknown blank)
- Click Calculate :- View the result with step-by-step formula
Example: You have 2M HCl and want 500mL of 0.5M solution. Solve for V₁: V₁ = (0.5 × 500) / 2 = 125 mL. Add water to reach 500 mL total.
