Atomic mass of Nitrogen is 14u

One atomic mass of nitrogen contain

6.022×10^23

The atom of nitrogen 14u is 6.022×10^23

So, one atom is atomic mass is

=14÷6.022×10^23

Now, in 0.5 moles the atom of nitrogen is

=6.022×10^23×0.5

Now mass of 0.5 Moles is

=14/6.022×10^23×6.022×10^23×0.5

=14×0.5

=7u

So, the mass of 0.5 moles of nitrogen is 7u.
