How does the conductivity of a strong electrolyte change upon dilution?

The molar conductivity of a $0.04 \text{ M}$ $AB_2$ type salt solution at $300 \text{ K}$ is $200 \text{ } \Omega^{-1} \text{ cm}^2 \text{ mol}^{-1}$. Find the conductivity.

The equivalent conductances of two strong electrolytes at infinite dilution in $H_2O$ (where ions move freely through a solution) at $25^{\circ}C$ are given below:
$\lambda^{\infty}_{CH_3COONa} = 91.0 \ S \ cm^2 \ eq^{-1}$
$\lambda^{\infty}_{HCl} = 426.25 \ S \ cm^2 \ eq^{-1}$
What additional information/quantity is needed to calculate $\lambda^{\infty}$ of an aqueous solution of acetic acid?

If the distance between two $Pt$ electrodes is $2 \, cm$,the cross-sectional area is $4.0 \, cm^2$,and the resistance is $25 \, \Omega$,find the molar conductivity of a $0.5 \, M$ solution.

The electrolytic conductance is a direct measure of

For which of the following electrolytes does the graph of $\Lambda_m$ vs $\sqrt{C}$ give a negative slope?
