We have taken a saturated solution of AgBr. K_sp of AgBr is 12 $$\times$$ 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, molar conductance of Ag⁺, Br^- and $$NO_3^-$$ are 6 $$\times$$ 10^-3 Sm² mol^-1, 8 $$\times$$ 10^-3 Sm² mol^-1 and 7 $$\times$$ 10^-3 Sm² mol^-1
