A conductivity cell has been calibrited with 0.01 M electrolyte solution (`k=1.25xx10^(-3)" S "cm^(-1)`) in the cell and the measured resistance is 800 ohms at `25^(@)C`. The cell constant will be :
A. `1.02 cm^(-1)`
B. `0.102 cm^(-1)`
C. `1.00 cm^(-1)`
D. `0.5 cm^(-1)`

Correct Answer - C
(c ) Specific conductance (k) `=(1)/(R )xx(1)/(a)`
`(l)/(a)=kxxR`
`=(1.25xx10^(-3)" ohm"^(-1)cm^(-1))xx(800" ohm")`
`=1.0 cm^(-1)`
