1. What is Molar Concentration?

Molar concentration (also called molarity) is a measure of the concentration of a chemical species, particularly of a solute in a solution. It is defined as the amount of substance in moles divided by the volume of solution in liters.

2. How Does the Calculator Work?

The calculator uses the molar concentration formula:

Where:

• \( c \) — Molar concentration (mol/L or M)
• \( n \) — Amount of substance (moles)
• \( V \) — Volume of solution (liters)

Explanation: The formula calculates how many moles of solute are present per liter of solution.

3. Importance of Molar Concentration

Details: Molarity is one of the most commonly used units of concentration in chemistry. It's essential for preparing solutions, stoichiometric calculations, and understanding reaction dynamics.

4. Using the Calculator

Tips: Enter the amount of substance in moles and the volume in liters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between molarity and molality?
A: Molarity is moles per liter of solution, while molality is moles per kilogram of solvent.

Q2: What are typical molarity values?
A: Concentrations range from millimolar (mM) to molar (M) depending on the application.

Q3: How do I prepare a solution with specific molarity?
A: Dissolve the calculated moles of solute in solvent, then dilute to the exact volume.

Q4: Does temperature affect molarity?
A: Yes, because volume changes with temperature while moles stay constant.

Q5: What's the relationship between molarity and normality?
A: Normality = Molarity × n (where n is the number of equivalents per mole).
