How It Works
Gas Volume at STP
Formula
V = n × 22.414 L/mol
At STP (0 C, 1 atm), one mole of any ideal gas occupies 22.414 liters.
Worked Example
Volume of 1 mole of O2 at STP.
moles_gas = 1
- 01V = n × 22.414
- 02V = 1 × 22.414
- 03V = 22.414 L
Frequently Asked Questions
What is STP?
Standard Temperature and Pressure: 0 C (273.15 K) and 1 atm (101.325 kPa).
Does 22.414 L apply to all gases?
To ideal gases. Real gases deviate slightly, especially at high pressures or low temperatures.
What about SATP?
SATP is 25 C and 1 bar, where the molar volume is 24.79 L/mol.
