Electrolytic and Metallic Conduction

A big irregular shaped vessel contained water, the sp. conductance of which was $2.56\times {10}^{-5}{\mathrm{mhocm}}^{-1}$. $500 \mathrm{g}$ of $\mathrm{NaCl}$ was then added to the water and the specific conductance after the addition of $\mathrm{NaCl}$, was found to be $3.10\times {10}^{-5}{\mathrm{mhocm}}^{-1}$. Find the capacity of the vessel if it is fulfilled with water. ( $\lambda \mathrm{NaCl}=149.9$). If your answer is $\mathrm{x}\times {10}^8\mathrm{cc}$ then $\mathrm{x}$ is:

The dissociation constant of $\mathrm{n}-$butyric acid is $1.6\times {10}^{-5}$ and the molar conductivity at infinite dilution is $380\times {10}^{-4}{\mathrm{Sm}}^2{ \mathrm{mol}}^{-1}.$ The specific conductance of the $0.01\mathrm{M}$ acid solution is :-

The specific conductance of an $\mathrm{N}/10 \mathrm{KCl}$ solution at $18°\mathrm{C}$ is $1.12\times {10}^{-2}\mathrm{mho} {\mathrm{cm}}^{-1}.$ The resistance of the solution contained in the cell is found to be $65 \mathrm{ohm}$. Calculate the cell constant $\left({\mathrm{cm}}^{-1}\right)$. (Note: Report your answer after multiplying with $100$ and rounding up to the nearest integer value.)

The minimum equivalent conductance in fused state is shown by -
