Solution:
At NTP 22400cc of N2O contains =6.02×1023 molecules ∴1ccN2O will contain =224006.02×1023 molecules
In N2O molecule, number of atoms =2+1=3
Thus, number of atoms =224003×6.02×1023 atoms =2241.8×1022 atoms
In N2O molecule, number of electrons =7+7+8=22
Hence, number of electrons =224006.02×1023×22 electrons =2241.32×1023 electrons
