Q. No.The limiting molar conductivities of Nal, NaNO3, and AgNO3 are \(\text { 12. } 7 \mathrm{~Sm}^2 \mathrm{~mole}^{-2}, 12 \mathrm{~Sm}^2 \mathrm{~mole}^{-2}\) and \(\text { 13.3 } \mathrm{Sm}^2 \mathrm{~mole}^{-2}\) respectively (all at 25°C). The limiting molar conductivity of Agl at this temperature is:
1. \(14~S~m^2mole^{-2}\)
2. \(16~S~m^2mole^{-2}\)
3. \(48~S~m^2mole^{-2}\)
4. \(12.6~S~m^2mole^{-2}\)
