Solution concentration calculator

Calculate moles, molarity, mass for a target solution and dilution volume.

Choose the quantity you need. Only inputs relevant to that calculation are required. Use molar mass in g/mol and the final solution volume, not the volume of solvent alone.

Calculate molarity and dilution

Convert solute mass and molar mass into moles and molarity for a prepared solution.

Use target concentration and final volume to estimate required mass or stock solution volume.

Quick start

Calculate molarity, solute mass, dilution or percentage concentration.

  1. Choose the calculation mode
  2. Enter the relevant masses, concentrations and volume units
  3. Calculate and export the result
✓ The tool runs directly in the browser and is ready for quick checks without installing software.
✓ Input can be cleared and recalculated immediately, which is useful for repeated small tasks.
✓ Use fullscreen mode when you need more space for long text, structured data or large result blocks.
✓ Copy buttons are available on generated output so results can be reused in code, documents or support chats.
✓ Most operations are deterministic: the same input and options produce the same output.
✓ For sensitive content, prefer local browser tools and review the result before sharing it further.
