$Al$ has double the conductivity compared to which metal?

Explain the effect of change in concentration on the conductivity of a solution.

How can the ionic conductivity of an unknown solution be determined?

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

$\wedge_{AgCl}^{\infty}$ can be obtained by:

$A$ conductivity cell is filled with $0.01 \ M \ KCl$ and gives a resistance of $484 \ \Omega$. The conductivity of the solution is $0.00141 \ \Omega^{-1} \ cm^{-1}$ at $25^{\circ}C$. What is the cell constant (in $cm^{-1}$)?
