Chemical Molarity Dilution Calculator
Calculate solution dilutions and concentration changes
Introduction
Solution dilution is the process of reducing concentration by adding solvent. The fundamental principle is that the amount of solute remains constant while the total volume increases, resulting in a lower concentration.
This calculator helps you determine how much water to add to achieve a desired final concentration, essential for preparing solutions of specific concentrations in laboratory and industrial applications.
How to Use
- Enter initial solution concentration (M)
- Input desired final concentration (M)
- Enter final solution volume (L)
- Click "Calculate Dilution" to get results
- Review volume of stock solution needed and water to add

Frequently Asked Questions
What is the dilution formula?
The dilution formula M₁V₁ = M₂V₂ is derived from the conservation of solute. The amount of solute (moles) remains constant before and after dilution, so initial concentration × initial volume = final concentration × final volume.
How do I calculate dilution factor?
The dilution factor is the ratio of initial to final concentration (M₁/M₂). It indicates how many times the solution has been diluted. A factor of 10 means the concentration is reduced by 10 times.
Why is dilution important?
Dilution is crucial for preparing solutions of specific concentrations, ensuring accuracy in experiments, safety in handling chemicals, and cost-effectiveness in industrial processes by using concentrated stock solutions efficiently.
