The `lamda^(@)` values of `KNO_(3)` and `LiNO_(3)` are 145.0 and 110.1 S `cm^(2)mol^(-1)` respectively. The `lamda^(@)` value of `K^(+)` ion is `73.5"S "cm^(2)mol^(-1)`. Calculate `lamda^(@)(Li^(+))`.

Explanation

`KNO_(2) rarr K^(+) + NO_(3)^(-)` …(1) `lamda_(e)^(0) 145.0S cm^(2) mol^(-1)`
`LiNO_(3) rarr Li^(+) + NO_(2)^(-)` ..(2) `lamda_(2)^(0) 110.1 S cm^(2) mol^(-1)`
`K^(+)` …(3) `lamda^(@)= 73.5 S cm^(2) mol^(-1)`
To final out the `lamda^(@)` for `Li^(+)`
`(2)-(1) + (3)`
`116.1 -145.0 + 73.5= 38.6S cm^(2)mol^(-1)`
