1 mole of ammonia gas at STP = 22.4L
therefore 1 ml ( 0.001L) of ammonia gas is 0.446428 x 10^-3 moles
1mole=6.022 × 10^23 molecules
therefore 0.446428 * 10^-3 moles=0.2688 x 10^20 molecules of ammonia
there are 4 atoms in 1 molecule of ammonia
thus no. of atoms =0.2688 x 10 ^20 x 4 =1.07535 x 10^20 atoms
