Dilution Calculator

C₁V₁ = C₂V₂ — solve for any unknown.

Introduction

Dilution Calculator — C₁V₁ = C₂V₂ — solve for any unknown. Enter C1 (mol/L) — blank if unknown, V1 (L) — blank if unknown, C2 (mol/L) — blank if unknown, V2 (L) — blank if unknown to get an instant, accurate result.

Formula

Dilution equation: C₁V₁ = C₂V₂. Enter any three values and it solves for the fourth.

Step-by-step

  1. Enter the C1 (mol/L) — blank if unknown.
  2. Enter the V1 (L) — blank if unknown.
  3. Enter the C2 (mol/L) — blank if unknown.
  4. Enter the V2 (L) — blank if unknown.
  5. Click Calculate to see your result instantly.

Real-world example

Example: With C1 (mol/L) — blank if unknown = 2, C2 (mol/L) — blank if unknown = 0.5, V2 (L) — blank if unknown = 4, the Dilution Calculator gives Unknown: v1, Value: 1.

Frequently Asked Questions

What does each variable mean?
C1/V1 are the concentration and volume before dilution; C2/V2 are the concentration and volume after dilution.
How many values do I need to enter?
Exactly three — leave the unknown one blank.
What inputs does the Dilution Calculator need?
You'll need to provide: C1 (mol/L) — blank if unknown, V1 (L) — blank if unknown, C2 (mol/L) — blank if unknown, V2 (L) — blank if unknown. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Dilution Calculator?
The Dilution Calculator applies the formula exactly as calculated — Dilution equation: C₁V₁ = C₂V₂. Enter any three values and it solves for the fourth. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Dilution Calculator free to use?
Yes, the Dilution Calculator is completely free, requires no signup, and runs instantly in your browser.
