1. What is Avogadro's Law?

Avogadro's Law states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. At standard temperature and pressure (STP), one mole of any gas occupies 22.4 liters.

2. How Does the Calculator Work?

The calculator uses Avogadro's Law equation:

Where:

• \( V \) — Volume of gas (liters)
• \( n \) — Number of moles (mol)
• 22.4 — Molar volume at STP (L/mol)

Explanation: This calculation assumes standard temperature (0°C) and pressure (1 atm) conditions.

3. Importance of Molar Volume Calculation

Details: Calculating molar volume is essential in stoichiometry, gas law problems, and determining quantities in chemical reactions involving gases.

4. Using the Calculator

Tips: Enter the number of moles. The value must be greater than 0. The result will be the volume in liters at STP conditions.

5. Frequently Asked Questions (FAQ)

Q1: What are STP conditions?
A: Standard Temperature and Pressure: 0°C (273.15K) and 1 atmosphere (101.325 kPa) pressure.

Q2: Does this work for all gases?
A: Yes, Avogadro's Law applies to all ideal gases at the same temperature and pressure.

Q3: What if conditions aren't at STP?
A: You would need to use the ideal gas law (PV = nRT) for non-STP conditions.

Q4: How accurate is the 22.4 L/mol value?
A: It's an experimentally determined value that applies to ideal gases at STP. Real gases may show slight deviations.

Q5: Can I use this for liquid or solid substances?
A: No, Avogadro's Law specifically applies to gases. Solids and liquids have different molar volumes.
