Solution

The atomic mass of an element is the mass of one atom of that element. In this case, we are given that 6.02 × 10^23 atoms of nitrogen have a mass of 14.0 g.

This number, 6.02 × 10^23, is known as Avogadro's number, and it represents the number of atoms in one mole of a substance.

So, if 6.02 × 10^23 atoms (or one mole) of nitrogen have a mass of 14.0 g, then the atomic mass of nitrogen is 14.0 g/mole.

This is because the atomic mass is defined as the mass of one mole of that element. So, the atomic mass of nitrogen is 14.0 g/mole.
