FAQ

What is the molar mass of N?

M(N) = 14.007 g/mol

Why is the molar mass of nitrogen 14.007 and not 28?

14.007 g/mol is the mass of one mole of N atoms. Elemental nitrogen is made of N₂ molecules: M(N₂) = 2 × 14.007 = 28.014 g/mol (28 in school problems); in SI units, 0.028014 kg/mol. In a problem about the gas, the molar mass of nitrogen is usually M(N₂).

How many grams are in 2 moles of N?

m = n × M = 2 mol × 14.007 g/mol = 28.014 g.
