of atoms in NH₃ = (1 + 3) = 4 x 100/17 x 6.022 x 10²³ = 141.69 x 10²³ atoms. Therefore, NH₃ has more atoms than N₂.
Thankyou and have a nice day......

Correct option is A)
(i) 100g N 2 contains = 28 moles
Number of molecules = 28/100 ×6.022×10^23
Number of atoms = 28/100×6.022×10^23×2
=43.01×10^23
(ii) 100g NH 3
=
17
