Solution Concentration Calculator
Calculate molarity, molality, and other concentration units for solutions
Introduction
Solution concentration describes the amount of solute dissolved in a solvent. Different units are used depending on the application: molarity (moles per liter), molality (moles per kilogram of solvent), mass percentage, and parts per million (ppm).
This calculator helps you convert between different concentration units and determine the exact composition of your solution for laboratory, industrial, or educational purposes.
How to Use
- Enter the mass of solute (grams)
- Input the molar mass of solute (g/mol)
- Enter the total solution volume (liters)
- Click "Calculate Concentration" to get all units
- Review molarity, molality, mass percentage, and ppm values

Frequently Asked Questions
What's the difference between molarity and molality?
Molarity is moles of solute per liter of solution, while molality is moles of solute per kilogram of solvent. Molarity changes with temperature, molality doesn't.
When should I use ppm?
PPM (parts per million) is used for very dilute solutions, typically in environmental monitoring, water quality testing, and trace analysis where concentrations are very low.
How does temperature affect concentration?
Temperature affects solution volume through thermal expansion, changing molarity. Molality is temperature-independent as it's based on solvent mass, not volume.
