Explanation:
By Avogadro law,
22.4 liter of any gas at STP=1mole
=6.022×10
23
molecules of gas
=NA (Avogadro number)
So, in 67.2 L of NH
3
=?
22.4 L of NH
3
=N
A
1 L of NH
3
=
22.4
NA
67.2 L of NH
3
=
22.4
67.2
×NA
=3N
A
molecules
Now, each molecule contain 4 atoma
Number of atoms =4×3N
A
=12N
A
atoms
