The resistance of ` aN//10KCI` solution is ` 245 Omega`. Calculate the equivalent conductance of the solution if the electrodes in the cell are `4 cm` apart and each haveing an area of ` 7.0 sq.cm`.

Options

A. `23. 32 cm^2 eq^(-1)`
B. `23. 23 S m^2 eq^(-1)`
C. `2. 332 S cm^2 eq^(-1)`
D. None of these

Answer

A

Explanation

` 245 = 1/(Lambda_(eq)) xx 4/7 ( 1000)/(0.1) rArr Lambda_(eq) = 23.32 S cm^2 eq^(-1)`.
