What is the molar mass of nitrogen?

The molar mass of nitrogen (N₂) is 28.02 g/mol.

Here's a breakdown:

Nitrogen exists primarily as a diatomic molecule (N₂). To calculate its molar mass, we need the atomic mass of a single nitrogen atom.

• Atomic mass of nitrogen (N): Approximately 14.01 amu (atomic mass units)
• Molecular mass of nitrogen (N₂): 2 x 14.01 amu = 28.02 amu
• Molar mass of nitrogen (N₂): 28.02 g/mol

The molar mass represents the mass of one mole (6.022 x 10²³ molecules) of a substance. Therefore, one mole of nitrogen gas (N₂) has a mass of 28.02 grams.
