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 $S \ cm^{2} \ mol^{-1}$?

The specific conductance of $0.05 \ M$ $NaOH$ solution is $0.0115 \ S \ cm^{-1}$. What is its molar conductance $(\Lambda_{m})$ in $S \ cm^2 \ mol^{-1}$?

How is the cell constant determined?

Given below are two statements :
Statement $I :$ The limiting molar conductivity of $KCl$ (strong electrolyte) is higher compared to that of $CH_{3}COOH$ (weak electrolyte).
Statement $II :$ Molar conductivity decreases with decrease in concentration of electrolyte.
In the light of the above statements,choose the most appropriate answer from the options given below:

Which of the following statements is incorrect with respect to metallic or electronic conductivity?

The resistance of a $0.5 \, M$ solution of an electrolyte in a cell was found to be $50 \, \Omega$. If the electrodes in the cell are $2.2 \, cm$ apart and have an area of $4.4 \, cm^2$,then the molar conductivity (in $S \, m^2 \, mol^{-1}$) of the solution is:
