1 molecule of NH3 contains 4 atoms
therefore 1 mole of NH3 contains 4 moles of atom
As 1 mole =6.022*10 raise to 23 atoms.
1 mole of ammonia contain=4*6.022*10 raise to 23
As we know at STP.1 mole of any gas occupies a constant volume i.e 22.4
Hence in 22.4 L contain →24.08*10 raise to 23
therefore 1 L contain →(24.08 × 10^23)/22.4 atoms (^ is for raise to)
therefore 10 L contain→(1.07 × 10^23) * 10 atoms
Hence 10 L of ammonia gas contain 1.07*10^23 and we can also say
1.07*10^24
