The molar mass of nitrogen is 14.01 grams per mole (g/mol).
Nitrogen is a diatomic molecule (N2) in its most common form in the atmosphere. Each nitrogen atom has an atomic mass of approximately 14.01 g/mol. Since there are two nitrogen atoms in one molecule of nitrogen gas, you would multiply the atomic mass by 2 to find the molar mass of nitrogen gas:
14.01 g/mol × 2 = 28.02 g/mol
Therefore, the molar mass of nitrogen gas (N2) is approximately 28.02 g/mol, which is often rounded to 28.00 g/mol for simplicity in calculations. This value is essential in chemistry for converting between grams and moles when performing stoichiometric calculations.
