Which among the following concentrations of $KCl$ solution is not used to determine the cell constant of a conductivity cell?

The electrical conductance of unit volume $(1 \ cm^3)$ of solution is called as

The resistance of a conductivity cell filled with $0.1 \ M$ $KCl$ solution is $100 \ \Omega$ and the conductivity is $1.70 \times 10^{-4} \ S \ cm^{-1}$. What is the cell constant of the cell (in $cm^{-1}$)?

Assertion: Electrical conductivity of copper increases with increase in temperature.
Reason: The electrical conductivity of metals is due to the motion of electrons.

The resistance of a conductivity cell with cell constant $1.14 \, cm^{-1}$,containing $0.001 \, M \, KCl$ at $298 \, K$ is $1500 \, \Omega$. The molar conductivity of $0.001 \, M \, KCl$ solution at $298 \, K$ in $S \, cm^{2} \, mol^{-1}$ is ...... . (Integer answer)
