Here's how to calculate the moles of nitrogen gas (N₂) given 11.2 liters:

Understanding the Concepts

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

* Nitrogen Gas: Nitrogen exists as a diatomic molecule (N₂).

Calculation

1. Divide the given volume by the molar volume:

11.2 L / 22.4 L/mol = 0.5 mol

Therefore, 11.2 liters of nitrogen gas (N₂) contains 0.5 moles.
