Question

Conductance of `0.1` M KCl (conductiviy = `X ohm^(-1) cm^(-1)`) filled in a conductivity cell is Y `ohm^(-1)` If the conductance of 0.1 M NaOH filled in the same cell is Z `ohm^(-1)` the molar conductance of NaOH will be
A. `10^(3)(XZ)/Y`
B. `10^(4) (XZ)/Y`
C. `10(XZ)/Y`
D. `0.1(XZ)/Y`

Answer 1

Correct Answer - B
Conductivity (x)=conductance (c) x cell constant
Cell constant `=x/y`
`lambda=(kxx1000)/M=((x/yxxz)xx1000)/(0.1)=(xz)/yxx10^(4)`
