<span>1.0 gram (g) of electrons would contain 10^27 electrons
Electrons have an electric charge of −1.602×10−19 coulomb
so total charge of 1 g electrons = -1.602 x 10^-19 x 10^27 = -1.602 x 10^8</span>
Energy (E) = Planck's constant (h) * frequency (nu)

therefore, frequency ~
Because your eyes will make it seem that there's more volume I'm guessing.
Answer:
Electrical Conductivity is 3200 
Solution:
As per the question:

Mobility of electrons, 
Mobility of holes, 
Charge, Q = 
Now,
The formula for the conductivity is given by:
