1)So, in one mole of nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2 . But since each individual molecule consists of 2 atoms of nitrogen, the number of moles of nitrogen atoms will be twice that of nitrogen gas molecules. Alternatively, you can express this as 2×NA , where NA is Avogadro's constant.

2)There are 4 atoms in a single molecule of P4. So, one mole of P4 contains 4 x Na = 4 x 6.022 x 10²³

3)first of all we need to calculate the no.of moles of water molecule I.e 0.05 gm of H2O

molecular weight of H2O =18gm

no.of moles = wt/gram molecular weight

=0.05/18

=0.0027

no.of molecules=no.of moles x Na

==>0.0027 x 6.023 x 10²³

= 0.016 x 10²³

no.of atoms in water molecule =3

===>3 x 0.016 x 10²³

=0.0487 x 10²³
