1.	The molar conductance of NaCl, HCl and `CH_(3)COONa` at infinite dilution are 126.45, 426.16 and 91 `ohm^(-1) cm^(2) mol^(-1)` respectively. The molar conductance of `CH_(3)COOH` at infinite dilution is :A. `201. 28 ohm^(-1) cm^(2)`B. `390 . 71 ohm ^(-1) cm^(2)`C. `698.28 ohm^(-1) cm^(2)`D. `540 ohm^(-1) cm^(2)`.
Answer» Correct Answer - B `Lambda_(C_(2) H_(5) COOH)^(@) = Lambda_(C_(2) H_(5) COONa)^(@) + Lambda_(HCl)^(@) - Lambda_(NaCl)^(@)` `= 91 + 426.16 - 126. 45` `= 390. 71 ohm^(-1) cm^(2)` .
