Which of the following decreases on dilution of an electrolytic solution?

At $298 \text{ K}$, the specific conductance $(\kappa)$ of a $0.0020 \text{ M } NaCl$ solution is $2.50 \times 10^{-4} \text{ S cm}^{-1}$. Calculate the molar conductivity $(\Lambda_m)$ of the solution in $\text{S cm}^2 \text{mol}^{-1}$.

If the resistivity of a $0.8 \ M \ KCl$ solution is $2.5 \times 10^{-3} \ \Omega \ cm$,calculate the molar conductivity of the solution.

If the conductance and specific conductance of a solution are both $1$,then its cell constant would be:

Electrical conductance due to all the ions in $1 \ cm^3$ of a given solution is called as

For a saturated solution of $CaF_2$,choose the correct relationship-
