Question

If the atomic weight of nitrogen is 14.0, what is the mass of one mole of nitrogen gas (n2)?

Answer 1

The molar mass of a molecule is the sum of the molar masses of its elements. The elemental form of nitrogen, N2, is made up of two nitrogen molecules. The atomic weight of an element is the number of grams in one mole of that atom. Since nitrogen's atomic mass is 14.0, there are 14.0 grams of nitrogen in one mole of nitrogen. N2 would be double that, since there are two nitrogen atoms. Therefore, the mass of one mole of nitrogen gas (N2) is 28.0 grams.

Answer 2

The mass of one mole of nitrogen will be 28 g.

What is mass?

A physical body's mass is the amount of matter it contains. It's also a measure of inertia if a net force would be injected into the body.

Calculation of mass of N2.

The atomic mass of N = 14 g

The atomic mass of N-2 = 28 g.

Therefore, the mass of one mole of N2 will be 28 g.
