📖 How to Use
- Formula:
C₁ × V₁ = C₂ × V₂(stock concentration × stock volume = final concentration × final volume) - Enter any three values, leave one blank, and click Calculate
- Molarity mode: units in mol/L and mmol/L, ideal for chemistry lab prep
- Percent mode: units in %, for weight/volume (w/v%) dilutions
- Custom units mode: flexible units for ppm, mg/mL, or any concentration
- Results include the dilution factor and solvent volume to add
