📐 Calculation Principle

Dilution Identity: C₁V₁ = C₂V₂

C₁ = stock concentration, V₁ = required stock volume
C₂ = target concentration, V₂ = total water volume
Unit equivalence: ppm = mg/L
Density approximation: 1 g/mL (aqueous solution)

💡 Example

Example: Mix 10 liters of 500 ppm working solution

Stock concentration: 100 g/L
Target concentration: 500 ppm
Total water: 10 L
Result: 50 mL stock needed
