As 1 molecule NH3 contain 4 atoms.
Therefore 1 mole of NH3 contain 4 moles of atoms.
As 1 mole = 6.022 × 10 atoms.
Therefore, 1 mole of ammonia contain = 4 × 6.022 × 10 atoms
. As we known at STP. 1 mole of any gas occupies a constant volume
i.e. 22.4 L Hence in 22.4 L contain → 24.08 × 10 atoms
∴ 1 L contain → (24.08 × 10 ) / 22.4 atoms
∴ 10 L contain → (1.07 × 10 ) × 10 atoms
Hence 10 Liter of ammonia gas contain 10.7 × 10 atoms or
we can say 1.07× 10 atoms
