The molar conductivity of a 0.5 mol `dm^(-1)` solution with electrolytic conductivity of `5.76 xx 10^(-1) S cm^(-1)`

A

`0.086 S cm^(2) mol^(-1)`

B

`28.8 S cm^(2) mol^(-1)`

C

`2.88 S cm^(2) mol^(-1)`

D

`11.52 S cm^(2) mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Concentration = `0.5 "mol" dm^(-3)`, K = `5.76 xx 10^(-3) S cm^(-1)`
T = 298 K `lambda_(H) = ( K xx 1000)/M`
`=(5.76 xx 10^(-2))/0.5 = 11.52 S cm^(2) "mol"^(-1)`
