Question

Calculate the number of electrons in 22 gram co2

Answer 1

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
