Molarity / Dilution (C₁V₁ = C₂V₂)

Calculate unknown concentration or volume when diluting a solution.

---

Formula

C₁ × V₁ = C₂ × V₂

Units must be consistent (both volumes in same unit).

Instructions

  • Enter any three values, leave the unknown blank.
  • The calculator will solve for the missing one.
  • For molarity, ensure concentrations are in mol/L (M).
