Step-by-step working
The formula
C₁V₁ = C₂V₂
| Symbol | Meaning |
|---|---|
| C₁,V₁ | Concentration and volume of transferred stock solution. |
| C₂,V₂ | Concentration and total volume after dilution. |
When to use this calculator
The relationship follows from n = CV when the amount of solute transferred is unchanged.
Worked example
The page opens with these example values. The result below is pre-generated for reference.
- V₁ = C₂V₂/C₁ = 0.1 × 250 / 1 = 25 cm³
25 cm³
Common mistakes
- V₂ is the final total solution volume, not the volume of solvent added.
