Molarity Dilution Calculator
The Molarity Dilution Calculator is an advanced yet simple online chemistry tool designed to help users quickly solve dilution problems involving molarity and volume relationships. It is widely used by students, teachers, and laboratory professionals to calculate initial concentration, final concentration, initial volume, final volume, dilution factor, and solvent required.
In chemistry, dilution is a fundamental process used to reduce the concentration of a solution while keeping the amount of solute constant. Instead of solving equations manually, this calculator automates the process using the standard dilution equation and provides instant, accurate results.
What is Molarity Dilution?
Molarity dilution refers to the process of changing the concentration of a solution by adding solvent without changing the number of moles of solute.
The basic equation used is:
C₁V₁ = C₂V₂
This is one of the most important relationships in solution chemistry and is part of the widely used concept of Dilution Formula.
It ensures that the amount of solute remains constant before and after dilution.

C₂ = (C₁ × V₁) / V₂
Result:
C₂ = 0.5 M
Example 2: Calculate Final Volume (V₂)
- C₁ = 2 M
- V₁ = 50 mL
- C₂ = 0.5 M
Formula:
V₂ = (C₁ × V₁) / C₂
Result:
V₂ = 200 mL
Example 3: Calculate Initial Concentration (C₁)
- C₂ = 0.25 M
- V₂ = 400 mL
- V₁ = 100 mL
Formula:
C₁ = (C₂ × V₂) / V₁
Result:
C₁ = 1 M
Example 4: Calculate Initial Volume (V₁)
- C₁ = 3 M
- C₂ = 1 M
- V₂ = 150 mL
Formula:
V₁ = (C₂ × V₂) / C₁
Result:
V₁ = 50 mL
