Understanding the Concept

* Molar Volume: At standard temperature and pressure (STP: 0°C and 1 atm), one mole of any ideal gas occupies 22.4 liters.

Calculation

Since 22.4 L is the molar volume of an ideal gas at STP, 22.4 L of N₂ represents 1 mole of nitrogen gas.

Therefore, 22.4 L of N₂ contains 1 mole of N₂.
