Answer:
No of moles of Co
2
in 100gm
n =
44
100
= 2.28
total no. of moles = 2.28 × N
A
so electron will be = 22× 2.28 ×N
A
= 22 × 2.28 × × 6.023 ×10
23
= 3.02 ×10
25
(2)
(a)
q = ne
n× 1.6×10
−19
= 0.32 ×10
−18
= 3.2 ×10
−17
n = 2 so possible
(b)
n ×1.6×10
19
= 0.64 ×10
20
= 0.64 ×10
−17
here n < 1
so not possible
(c)
n×1.6×10
−19
= 4.8 ×10
−21
n = 3 ×10
−2
= 0.03
n < 1
so not possible
