Text Solution

Verified by Experts

Taking the square root of concentration we obtain :

A plot of `Lambda_(m)` (y-axis) and `C^(1//2)` (x-axis) is shown below, it can be seen that it is nearly a straight line. From the intercept `(C^(1//2)=0)`, we get, `Lambda_(m)^(@)="150.0 S.cm"^(2)."mol"^(-1)` and
`A=-slope = "87.46 S.cm"^(2)."mol"^(-1)("mol.L"^(-1))^(1//2)`
