A

`"271.8cm"^(2).eq^(-1)`

B

`"67.95S.cm"^(2).eq^(-1)`

C

`"542.6S.cm"^(2).eq^(-1)`

D

`"135.9 S.cm"^(2).eq^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`"1.359 S.cm"^(2)."eq"^(-1)`
`Lambda_([(COO^(-))_(2)Na^(+)K^(+)])^(@)`
`=(1)/(2)[lambda_((COO^(-))_(2))^(@)+lambda_((Na^(+)))^(@)+lambda_((K^(+)))^(@)]`
`=(1)/(2)(148.2+73.5+50.1)=(1)/(2)xx271.8`
`="135.9 S.cm"^(2)."eq"^(-1)`
