Solution Concentration Calculator – Molarity, Molality & More

Solution concentration is a measure of how much solute is dissolved in a solvent to create a solution. Different concentration units are used depending on the application and the properties being studied.

Concentration Types

• Molarity (mol/L): The number of moles of solute per liter of solution. It's commonly used in chemistry for reactions in solution.
• Molality (mol/kg): The number of moles of solute per kilogram of solvent. It's useful for studying colligative properties of solutions.
• Percent by Mass (% w/w): The mass of solute divided by the mass of the solution, multiplied by 100. Often used in industrial and pharmaceutical applications.
• Percent by Volume (% v/v): The volume of solute divided by the volume of solution, multiplied by 100. Commonly used for liquid-liquid solutions like alcoholic beverages.
• Parts Per Million (ppm): The mass of solute divided by the mass of solution, multiplied by 1,000,000. Used for very dilute solutions, such as in environmental analysis.
