Is 1 Mol of Gas 22.4 L?

Yes, 1 mole of any ideal gas occupies 22.4 liters at standard temperature and pressure (STP): 0°C (273.15 K) and 1 atmosphere pressure.

Molar Volume Law:

• At STP: 1 mole of any gas = 22.4 L
• Applies to: All ideal gases
• Basis: Avogadro's law (equal volumes contain equal numbers of molecules at same conditions)

STP Conditions:

• Temperature: 0°C or 273.15 K
• Pressure: 1 atm or 101.325 kPa

Examples:

• 1 mol O₂ = 22.4 L at STP
• 1 mol N₂ = 22.4 L at STP
• 1 mol CH₄ = 22.4 L at STP

Important Note:

• Only true at STP
• Different conditions require ideal gas law (PV = nRT)

Importants Points:

• At STP: 1 mole gas = 22.4 L
• Conditions: 0°C and 1 atm
• Applies to: All ideal gases
