Specific conductance of 0.1 M nitric acid is `6.3xx10^(-2)` `ohm^(-1)` `cm^(-1)` . The molar conductance of the solution is

A

630 `ohm^(-1)` `cm^(2)` `mol^(-1)`

B

315 `ohm^(-1)` `cm^(2)` `mol^(-1)`

C

6.300 `ohm^(-1)` `cm^(2)` `mol^(-1)`

D

63.0 `ohm^(-1)` `cm^(2)` `mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A

`k=6.3xx10^(-2)ohm^(-1)cm^(-1),C=0.1M`
`Lambda_m=kxx1000/C=6.3xx10^(-2)xx1000/0.1=630 ohm^(-1)cm^(2)mol^(-1)`
