Step 1:Number of electrons
No. of moles =
molecular weight
weight
=
44
100
=2.28
No. of molecules =nN
A
=2.28×6.023×10
23
=1.3732×10
24
molecules
Total No. of electrons =22×1.3732×10
24
=3.02×10
25
Step 2:Check all options
(i) Q=n
e
∴n=

Q
=
1.6×10
−19
0.32×10
−18
=2(possible)
(ii) n=
e
Q
=
1.6×10
−19
0.64×10
−20
=0.04
n<1
∴ It will not be possible.
(iii) n=
1.6×10
−19
4.8×10
−21
=0.03
n<1
It will not be possible.
