1.	The molar conductances of `NaCI, HCI` and `CH_3 COONa` at infinite dilution are `12.45, 426. 16` and ` 91 "ohm"^(-1) cm^2 "hol"^(-1)` respectively. The molar conductance of `CH_3COOH` at infinite dilution is .A. ` 201 .28 ohm^(-1) cm^2 "mol^"(-1)`B. ` 39071 "ohm"^(-1) cm^2 "mol"^(-1)`C. ` 698.28 "ohm"^(-1) cm^2 "mol"^(-1)`D. ` 540.48 ohm^(-1) cm^2 mol^(-1)`
Answer» Correct Answer - B ` ^^_m^@ (CH_3COOH)` `= (CH_3COONa) + ^^@(HCl) -^^@ (NaCl)` `= 91 + 426 . 16 - 12 . 45` ` = 390. 71 "ohm"^(-1) cm^@ "mol"^(-1)`.
