The electronic conductance depends on

The electrodes of a conductivity cell are $3 \text{ cm}$ apart and have a cross-sectional area of $4 \text{ cm}^2$. The cell constant of the cell (in $\text{cm}^{-1}$) is

$A$ 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 $cm^{-1}$)?

Equivalent conductivity of $Cr_2(SO_4)_3$ is related to molar conductivity by the expression

The resistance of a conductivity cell filled with $0.1 \ M$ electrolyte solution is $100 \ \Omega$. The conductivity of this solution is $1.29 \ S \ m^{-1}$. If the resistance of the same cell filled with $0.02 \ M$ solution is $520 \ \Omega$,what is the molar conductivity of the $0.02 \ M$ solution?
