As we learnt in 

Conductivity -

Inverse of resistivity is called conductivity. \kappa = \frac{1}{\rho } 

- wherein

SI unit of Conductivity = Sm^{-1}

 

Transport number of Cl^{-}=0.505

but t_{cl^{-}}+t_{k^{+}}=1

t_{k^{+}}=1-0.505=0.495

\therefore Solution is 1


Option 1)

0.495

Correct

Option 2)

0.505

Incorrect

Option 3)

0.0495

Incorrect

Option 4)

Can't be determined

Incorrect
