#### Question

Conductivity of a solution is 6.23 x 10^{-5 } Ω^{-1}cm^{-1} and its resistance is 13710Ω. If the electrodes are 0.7cm apart, calculate the cross-sectional area of electrode.

#### Solution

ross-sectional area of electrode:

`k=1/R*l/a`

`a=1/R*l/k`

`a=1/13710*0.7/(6.23*10^-5)`

`a=0.82cm^2`

Is there an error in this question or solution?
