Molar Mass of N2

How to work out the molar mass of N2

1. Count the atoms of each element in N2: 2 N.
2. Multiply each count by the element's atomic weight: 2 × 14.007 = 28.014.
3. Add the results: 28.014 = 28.014 g/mol.

Frequently asked questions

What is the molar mass of N2?

The molar mass of nitrogen gas (N2) is 28.014 g/mol, so one mole of it weighs 28.014 grams.

How many moles are in 100 grams of N2?

100 g ÷ 28.014 g/mol = 3.570 mol.

Which element makes up most of the mass of N2?
