Resistance of a decinormal solution of a salt occupying a volume between Platinum electrodes 1.8 cm apart and 5.4 `cm^(2)` in area was found to be 32 ohm. Equivalent conductivity of solution in S `cm^(2)` `eq^(-1)` is

Options

A. 104.1 S `cm^(2)` `eq^(-1)`
B. 10.41 S `cm^(2)` `eq^(-1)`
C. 1.041 S `cm^(2)` `eq^(-1)`
D. 1041 S `cm^(2)` `eq^(-1)`

Answer

A

Explanation

Applying
`k=1/Rxxl/a=1/32xx1.8/5.4=0.01041` S `cm^(-1)`
We know
`Lambda_(eq)=kxx1000/"Normality"=0.01041xx1000/(1//10)=104.1 S cm^(2)eq^(-1)`
