Molar Concentration Formula:
| From: | To: |
Molar concentration (also called molarity) is a measure of the concentration of a chemical species in a solution, expressed as the amount of substance per unit volume of solution. It is one of the most common units used to quantify the concentration of a solution in chemistry.
The calculator uses the molar concentration formula:
Where:
Explanation: This formula calculates the concentration by dividing the number of moles of solute by the volume of the solution in liters.
Details: Molar concentration is fundamental in chemical reactions, solution preparation, stoichiometry calculations, and various laboratory applications. It helps determine reaction rates, equilibrium constants, and is essential for preparing solutions of precise concentrations.
Tips: Enter the amount of substance in moles and the volume in liters. Both values must be positive numbers. The calculator will compute the molar concentration in mol/L.
Q1: What is the difference between molarity and molality?
A: Molarity (c) is moles per liter of solution, while molality is moles per kilogram of solvent. Molarity is temperature-dependent, while molality is not.
Q2: How do I convert grams to moles?
A: Use the formula: moles = mass (g) / molar mass (g/mol). You need to know the molar mass of the substance.
Q3: What are typical concentration ranges?
A: Concentrations can range from very dilute (10⁻⁶ M) to concentrated (10+ M), depending on the application and solubility.
Q4: Why is molar concentration important in chemistry?
A: It allows precise quantification of reactants in solutions, enabling accurate stoichiometric calculations and reproducible experimental conditions.
Q5: Can I use different volume units?
A: Yes, but you must convert to liters first. Common conversions: 1 L = 1000 mL, 1 L = 1 dm³.
