1. What is Molar Concentration?

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. The SI unit is mol/m³, but mol/L is more commonly used in chemistry.

2. How Does the Calculator Work?

The calculator uses the molar concentration formula:

Where:

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

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

3. Importance of Concentration Calculation

Details: Knowing the exact concentration of solutions is essential for chemical reactions, preparing reagents, and performing titrations in laboratory work.

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: How do I convert grams to moles?
A: Divide the mass in grams by the molar mass of the substance.

Q3: What is a standard solution?
A: A solution with a precisely known concentration, often used in titrations.

Q4: Why is molarity temperature dependent?
A: Because volume changes with temperature, while moles remain constant.

Q5: How do I prepare a solution of specific molarity?
A: Dissolve the calculated moles of solute in less solvent, then dilute to the exact volume.
