Class 11 NEET Chemistry Some Basic Concepts Of Chemistry

As we know
22400cc of N2O contain 6.02×1023 molecules
∴ 1 cc of N2O contain ‌

6.02×1023

22400

molecules
since in N2O molecule there are 3 atoms
∴‌‌1cc‌N2O=‌

3×6.02×1023

22400

atoms
=‌

1.8×1022

224

atoms
No. of electrons in a molecule of
N2O=7+7+8=22
Hence, no. of electrons =‌

6.02×1023

22400

×22 electron
=‌

1.32
