Question

The specific conductance of 0-1M NaCl solution is `1.6xx10^(-2) ohm^(-1)cm^(-1)`. Its molar conductance in `ohm^(-1) cm ^(2) "mol"^(-1)` is
A. `1.06xx10^(2)`
B. ` 1.06xx10^(3)`
C. `1.06xx10^(4)`
D. `53`

Answer 1

Correct Answer - A
`k=1.06xx10^(-2)ohm^(-1)cm^(-1)`
Molarity =0.1 M
`lambda_(m)=(kxx1000)/("Molarity")=(1.06xx10^(-2)xx1000)/(0.1)`
`=1.06xx10^(2)ohm ^(-1)cm^(2)"mol"^(-1)`
