1.	At `25^(@)C`, the molar conductances at infinite dilution for the strong electrolytes `NaOH, NaCl " and " BaCl_(2) " are " 248 xx 10^(-4), 126 xx 10^(-4)" and " 280 xx 10^(-4) S m^(2) mol^(-1)` respectively. `Lamda_(m)^(@) Ba (OH)_(2) " in " S m^(2) mol^(-1)`A. `52.4 xx 10^(-4)`B. `524 xx 10^(-4)`C. `402 xx 10^(-4)`D. `262 xx 10^(-4)`
Answer» Correct Answer - B `Lamda_(m)^(@) Ba(OH)_(2) = Lamda_(m)^(@) BaCl_(2) + 2 Lamda_(m)^(@) NaOH - 2 Lamda_(m)^(@) NaCl` `= 280 xx 10^(-4) + 2 xx 249 xx 10^(-4) - 2 xx 126 xx 10^(-4)` `= 524 xx 10^(-4) S m^(2) mol^(-1)`
