Solution - Conductivity of a solution is 6.23 x 10-5  Ω-1cm-1 and its resistance is 13710Ω. If the electrodes are 0.7cm apart, calculate the cross-sectional area of electrode - HSC Science (Computer Science) 12th Board Exam - Chemistry

Question

Conductivity of a solution is 6.23 x 10-5  Ω-1cm-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?
