V = n × 22.4 L at STP (0 °C, 1 atm) for ideal gases — JEE standard
What each symbol means
| Symbol | What it stands for |
|---|---|
| V | Volume of gas (L) |
| n | Amount (mol) |
| V_m | Molar volume ≈ 22.4 L/mol at STP (1 atm, 0 °C) |
When to use this
Assumes ideal gas and standard pressure 1 atm; newer IUPAC STP (1 bar) uses ~22.7 L/mol — follow problem statement.
