The conductance of a salt solution (AB) ...

The conductance of a salt solution (AB) measured by two parallel electodes of area `100 cm^2` separated by 10cm was found to be `0.0001Omega^(-1)` . If volume enclosed between two electrode contain 0.1 mole of salt, what is the molar conductivity `(Scm^2mol^(-1))` of salt at same concentration:

A

10

B

0.1

C

0

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
`x=(l)/(A)=(10)/(100)=0.1`
`C=0.0001S`
` V=100xx10=1000 Cm^(3) =1L `
` =((0.1xx0.0001)xx1000)/(0.1)`
` =0.1 S cm ^(2) mol^(-1)`
