For an electrolyte solution of `0.05 mol L^(-1)` , the conductivity has been found to be `0.0110S cm^(-1)`. The molar conductivity is

Options

A. `0.055 S cm^(2) mol^(-1)`
B. `550 S cm^(2) mol^(-1)`
C. `0.22 S cm^(2) mol^(-1)`
D. `220 S cm^(2) mol^(-1)`

Answer

D

Explanation

`Lambda_(m) = (k xx 1000)/(M) = (0.0110 xx 1000)/(0.05)`
`= 220 S cm^(2) mol^(-1)`
