The equivalent conductances of two strong electrolytes at infinite dilutution in `H_2O` ( where ion move freely through a solution ) at `25^(@)C` are give below `Lambda_(CH_3COONa)^(0) = 91.0 S cm^(2)//"equiv", Lambda_(HCl)^(0) = 426.2 S cm^(2)//"equiv"` What additional information / quantity one needs to calculate `Lambda^(0)` of an aqueous solution of acetic acid ?

Options

A. `Lambda^(@)`of `CH_(3)COOK`
B. `Lambda^(@)` of `H^(+)`
C. `Lambda^(@)` of `ClCH_(2)COOH`
D. `Lambda^(@)` of NaCl
