1. What is the Mole Formula?

The mole formula (n = M × V) calculates the amount of substance in moles from its concentration and volume. It's a fundamental equation in chemistry for quantitative analysis.

2. How Does the Calculator Work?

The calculator uses the mole formula:

Where:

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

Explanation: The formula simply multiplies concentration by volume to determine the number of moles of solute present in a solution.

3. Importance of Mole Calculation

Details: Calculating moles is essential for preparing solutions, stoichiometric calculations in reactions, and determining reactant quantities in chemical processes.

4. Using the Calculator

Tips: Enter concentration in mol/L and volume in liters. Both values must be positive numbers. The result will be in moles.

5. Frequently Asked Questions (FAQ)

Q1: What if my volume is in milliliters?
A: Convert mL to L by dividing by 1000 before entering the value (1 L = 1000 mL).

Q2: Can I use this for gases?
A: This formula is for solutions. For gases, use the ideal gas law (PV = nRT).

Q3: What about very dilute solutions?
A: The formula works at any concentration, but for very dilute solutions (nM or pM), consider using scientific notation.

Q4: Does temperature affect the calculation?
A: Temperature affects concentration if volume changes, but the formula itself is temperature-independent.

Q5: How precise should my measurements be?
A: Precision depends on your application. Analytical chemistry often requires 4+ significant figures.
