Question

The resistance of `0.5` N solution of an electroolyte in a conductivity cell was found to be 45 ohms. If the electrodes in the cell are `2.2` cm apart and have an area of `3.8cm^(2)` then the equivalent conductance (in `Scm^(2)eq^(-1)`) of a solution is
A. `25.73`
B. `15.75`
C. `30.75`
D. `35.75`

Answer 1

Correct Answer - A
`^^_(eq)=(kxx1000)/(N)" "k=(1)/(r)xx(l)/(a)`
