1. What Is Molarity?

Molarity (M) is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution. It is one of the most commonly used units in chemistry for expressing concentration.

2. How Does The Calculator Work?

The calculator uses the molarity formula:

Where:

• \( M \) — Molarity (mol/L)
• \( n \) — Number of moles (mol)
• \( V \) — Volume of solution (L)

Explanation: This formula calculates the concentration of a solution by dividing the amount of substance (in moles) by the volume of the solution (in liters).

3. Importance Of Molarity Calculation

Details: Molarity is essential in chemical reactions, solution preparation, titration calculations, and various laboratory procedures where precise concentration measurements are required.

4. Using The Calculator

Tips: Enter the number of moles and volume in liters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between molarity and molality?
A: Molarity 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: Can I use different volume units?
A: The calculator requires liters. Convert milliliters to liters by dividing by 1000 (1 mL = 0.001 L).

Q4: What is a standard solution?
A: A solution whose concentration is accurately known. Standard solutions are used in titrations and analytical chemistry.

Q5: How does dilution affect molarity?
A: When you dilute a solution, the number of moles remains constant but the volume increases, so the molarity decreases proportionally.
