The resistance of 0.05 `MCH_(3)COOH` solution is found to be 100ohm. If the cell constant is 0.037 `cm^(-1)` , the molar conductivity of the solution is

A

`3.7ohm^(-1)cm^(2)"mol"^(-1)`

B

`74ohm^(-1)cm^(2)"mol"^(-1)`

C

`7.4ohm^(-1)cm^(2)"mol"^(-1)`

D

`37ohm^(-1)cm^(2)"mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`^^_(m)^(0)(MgCl_(2))=lambda^(0)(Mg^(2+))+2lambda^(0)(Cl^(-))`
`=106.12+2xx76.34`
`=258.8 ohm^(-1)cm "mol"^(-1)`
