1. What is Molarity?

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

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 solute (in moles) by the volume of the solution (in liters).

3. Importance of Molarity Calculation

Details: Molarity is essential for preparing solutions with precise concentrations, conducting chemical reactions, and performing quantitative analysis in laboratories and industrial processes.

4. Using the Calculator

Tips: Enter the number of moles and volume in liters. Both values must be positive numbers. The calculator will compute the molarity in mol/L.

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: What are common molarity ranges?
A: Concentrated solutions can be 10-18 M, standard solutions 0.1-1 M, and dilute solutions 0.001-0.1 M.

Q3: How do I convert grams to moles?
A: Divide the mass in grams by the molar mass of the substance: moles = mass (g) / molar mass (g/mol).

Q4: Can I use different volume units?
A: Yes, but convert to liters first. 1 L = 1000 mL = 1000 cm³.

Q5: When is molarity not appropriate?
A: For temperature-sensitive applications or when dealing with solutions where volume changes significantly with temperature.
