We have taken a saturated solution of AgBr. K_sp of AgBr is 12 * 10^-14. If 10^-7 mole of AgNO₃ are added to 1 litre of this solution find conductivity (specific conductance) of this solution in terms of 10^-7 S m^-1 units.

Given:  ${\lambda }_{\left(A{g}^{+}\right)}^o=6*10^{-3}S{m}^{2}mo{l}^{-1}$  

${\lambda }_{\left(B{r}^{-}\right)}^o=8*10^{-3}S{m}^{2}mo{l}^{-1}$

${\lambda }_{\left(N{O}_3^{-}\right)}^o=7*10^{-3}S{m}^{2}mo{l}^{-1}$
