1. What is the Concentration to Moles Formula?

The concentration to moles formula (n = C × V) calculates the amount of substance (in moles) from its concentration (in mol/L) and volume (in L). This fundamental chemistry equation relates these three important quantities.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( n \) — Amount of substance (moles)
• \( C \) — Concentration (mol/L)
• \( V \) — Volume (L)

Explanation: The formula directly relates the three variables - multiplying concentration by volume gives the number of moles of solute in the solution.

3. Importance of Moles Calculation

Details: Calculating moles from concentration is essential for preparing solutions, stoichiometric calculations, and quantitative chemical analysis in laboratories and industry.

4. Using the Calculator

Tips: Enter concentration in mol/L and volume in liters. Both values must be positive numbers. The calculator will compute the amount of substance 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 mL = 0.001 L).

Q2: Can I use this for any solute?
A: Yes, as long as you know the molar concentration of your solution, the formula works for any solute.

Q3: What's the difference between moles and molarity?
A: Moles measure amount of substance, while molarity (M = mol/L) measures concentration - the amount per unit volume.

Q4: How precise should my measurements be?
A: Precision depends on your needs. For most laboratory work, 3-4 significant figures is typical.

Q5: Can I calculate concentration if I know moles and volume?
A: Yes, you can rearrange the formula: C = n/V.
