Which solution of $NaCl$ will show the highest resistance during the passage of current (in $N$)?

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 $CH_3COOH$?

The molar conductivities at infinite dilution for sodium acetate,$HCl$ and $NaCl$ are $91 \ S \ cm^2 \ mol^{-1}$,$425.9 \ S \ cm^2 \ mol^{-1}$ and $126.4 \ S \ cm^2 \ mol^{-1}$ respectively. The molar conductivity of acetic acid at infinite dilution is

The unit of molar conductivity is
