The limiting molar conductivities $\lambda^{0}$ for $NaCl$,$KBr$,and $KCl$ are $126$,$152$,and $150 \ S \ cm^{2} \ mol^{-1}$ respectively. What is the $\lambda^{0}$ for $NaBr$ in $S \ cm^{2} \ mol^{-1}$?

$A$ conductivity cell dipped in $0.05 \ M$ $KCl$ has a resistance of $600 \ \Omega$. If the conductivity is $0.0015 \ \Omega^{-1} \ cm^{-1}$,what is the value of the cell constant (in $cm^{-1}$)?

What is the $SI$ unit of molar conductivity?

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 dissociation constant of acetic acid is $1.6 \times 10^{-5}$ and molar conductance at infinite dilution is $380 \times 10^{-4} \, S \, m^2 \, mol^{-1}$. The specific conductance of $0.01 \, M$ acid solution is

The conductivity of a $0.05 \, M$ solution of a weak monobasic acid is $10^{-3} \, S \, cm^{-1}$. If $\lambda_{m}^{\infty}$ for the weak acid is $500 \, S \, cm^{2} \, mol^{-1}$,calculate the $K_{a}$ of the weak monobasic acid.
