Compouter the m olar conducitivity of a solution of `MgCl_(2)` at infi

1.	Compouter the m olar conducitivity of a solution of `MgCl_(2)` at infinite dilution. Given that `lambda_(Mg)^(2+)=106.12ohm^(-1)cm^(2)"mol"^(-1)` `lambda _(Mg)^(2+)=106.12ohm^(-1)cm^(2)"mol"^(-1)`A. 182.46`ohm^(-1)cm^(2)"mol"^(-1)`B. `258.8ohm^(-1)cm^(2)"mol"^(-1)`C. `212.24ohm^(-1)cm^(2)"mol"^(-1)`D. `152.68ohm^(-1)cm^(2)"mol"^(-1)`
Answer» Correct Answer - B `426.1=lambda_((H^(+))^(0))+lambda_((CH_(3)COO^(-)))^(0)` .......(ii) `126.5 =lambda_((Na^(+)))^(0)+lambda_((Cl^(-))^(0)` Adding eqn. (i) and (ii) and sub tracting eqn. iii we get `lambda_((H^(+))^(0))+lambda_((CH_(3)COO^(-)))^(0)=426.1+91.0-126.5` `=390.6ohm^(-1)cm^(2)"mol"^(-1)`
