Atomic weights of N= 14

then no of moles in 0.7g = 7/140 = 1/20 = 0.05 mole.

no of atoms will be in it...

1mole = 6.022×10^23

then no of atoms will be....

6.022×10^23 ×0.05 = 0.3011×10^23

3.011×10^22 Atoms...

In 1 atom no of electrons = 7

then....

no of total electrons = 7×3.011×10^22

2.1077×10^23 electrons....
