A saturated solution of AgBr (Ksp = 12×10 −14) is mixed with a 10 −7 M AgNO3 solution. Calculate the specific conductance of the resultant solution in units of (10 −7 Sm −1). Molar conductivity at infinite dilution Λ∞ in units of (Sm 2mol −1) for the following species is given:   Λ∞ Ag + = 6 × 10 −3,   Λ∞ NO3− = 7 × 10 −3,   Λ∞ Br − = 8 × 10 −3.
