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

Answer:
first calculate the moles of
C
O
2
= 100/44
= 2.27 mol
now number of electrons in
C
O
2
are obtained by adding total electrons in each of the three atoms i.e. two O and one C = 6+8+8
= 22
thus one mole of
C
O
2
has

6.022

23
electrons and 2.27 mol has
