The molar mass of nitrogen gas (N₂) is indeed 28.02 g/mol. This value is derived from the atomic mass of nitrogen.

Understanding Molar Mass

Molar mass represents the mass of one mole of a substance. A mole is a fundamental unit in chemistry, representing Avogadro's number (approximately 6.022 x 10²³) of particles (atoms, molecules, ions, etc.).

Calculating the Molar Mass of N₂

Nitrogen gas exists as a diatomic molecule, meaning each molecule contains two nitrogen atoms. The atomic mass of a single nitrogen atom is approximately 14.01 g/mol. Therefore, the molar mass of N₂ is calculated as follows:

• 2 atoms of nitrogen/molecule * 14.01 g/mol/atom = 28.02 g/mol

This means that one mole of nitrogen gas (N₂) has a mass of 28.02 grams. This value is crucial in various stoichiometric calculations in chemistry.
