How does electrolytic conduction differ from metallic conduction?

In an aqueous solution,how does specific conductivity of electrolytes change with the addition of water?

If $\Lambda^{0}_{NaOAc} = 91 \, S \, cm^{2} \, mol^{-1}$ and $\Lambda^{0}_{HCl} = 496.2 \, S \, cm^{2} \, mol^{-1}$,what additional value is required to calculate $\Lambda^{0}_{HOAc}$?

The limiting molar conductivities of $NaI$,$NaNO_3$ and $AgNO_3$ are $12.7$,$12.0$ and $13.3 \, mS \, m^2 \, mol^{-1}$,respectively (all at $25^{\circ} C$). The limiting molar conductivity of $AgI$ at this temperature is $.... \, mS \, m^2 \, mol^{-1}$.

At $25^oC$,the molar conductance of a $0.1 \ M$ aqueous solution of ammonium hydroxide is $9.54 \ \Omega^{-1} \ cm^2 \ mol^{-1}$ and at infinite dilution,its molar conductance is $238 \ \Omega^{-1} \ cm^2 \ mol^{-1}$. The degree of ionization of ammonium hydroxide at the same concentration and temperature is ........... $\%$.

The pair of electrolytes that possess the same value for the constant $(A)$ in the Debye-Huckel-Onsager equation,$\Lambda_{m} = \Lambda_{m}^{\circ} - A \sqrt{C}$ is
