The conductance of a 0.0015M aqueous solution of a weak monobasic acid was determined by using a conductivity acid was determined by using a cunductivity cell consisting of platinised pt electrodes. The distance between the electrodes is 120cm with an area of croos section of 1 `cm^(2)`. The conductance of this solution was found to be `5xx10^(-7)` S. the pH of the solution is 4. The value of limiting moalr conductivity `(A_(m)^(@))` of this weak monobasic acid in aqueous solution is `Zxx10^(2)S cm^(-1) "mol"^(-1)`. the value of Z is

Answer

`6xx10^(2)S cm^(-1) "mol"^(-1)`
