How to Use This Calculator

Enter initial concentration (C₁) and initial volume (V₁).
Set target concentration (C₂) for the diluted solution.
Review Final Volume (V₂), Solvent to Add (mL), and Dilution Factor.
Use the formula C₁V₁ = C₂V₂ — this calculator solves for V₂ automatically.

How the result changes with Target Concentration (C₂)

Target Concentration (C₂)	Final Volume (V₂)	Solvent to Add
10	10 mL	0 mL
35	2.857 mL	0 mL
65	1.538 mL	0 mL
90	1.111 mL	0 mL

What each input means

Initial Concentration (C₁): Molarity of the stock (concentrated) solution
Initial Volume (V₁): Volume of stock solution to use
Target Concentration (C₂): Desired final molarity after dilution — must be less than C₁

How this is calculated

Formula

C₁V₁ = C₂V₂
