Resistance of $0.1\, M\, KCl$ solution in a conductance cell is $300\, \Omega$ and conductivity is $0.013\, S\, cm^{-1}$. The value of cell constant is

At $25^o C$,the molar conductivity of a $0.1 \, N \, CH_3COOH$ solution is $80 \, S \, cm^2 \, mol^{-1}$ and the molar conductivity at infinite dilution is $400 \, S \, cm^2 \, mol^{-1}$. What is the degree of dissociation $(\alpha)$ of $CH_3COOH$?

Which of the following ions has the maximum molar ionic conductivity in aqueous solution?

Given below is the plot of the molar conductivity vs $\sqrt{concentration}$ for $KCl$ in aqueous solution. If,for the higher concentration of $KCl$ solution,the resistance of the conductivity cell is $100 \ \Omega$,then the resistance of the same cell with the dilute solution is '$x$' $\Omega$. The value of $x$ is $............$ ($Nearest$ $integer$)

Equivalent conductance of an electrolyte containing $NaF$ at infinite dilution is $90.1 \, \Omega^{-1} \, cm^2$. If $NaF$ is replaced by $KF$,what is the value of equivalent conductance? ........... $\Omega^{-1} \, cm^{2}$

The molar conductivities of $KCl$,$NaCl$ and $KNO_3$ are $100$,$120$ and $90 \ S \ cm^2 \ mol^{-1}$ respectively. The molar conductivity of $NaNO_3$ would be .......... $S \ cm^2 \ mol^{-1}$.
