Electrochemistry Questions

The cell, $\text{Zn}|{\text{Zn}}^{2+}(1\text{M})||{\text{Cu}}^{2+}(1\text{M})|\text{Cu}$, $E_{\text{cell}}^0=1.10\text{V}$, was allowed to be completely discharged at $298\text{K}$. The relative concentration of ${\text{Zn}}^{2+}$ to ${\text{Cu}}^{2+}$, $\frac{[{\text{Zn}}^{2+}]}{[{\text{Cu}}^{2+}]}$, is:

The equivalent conductances of two strong electrolytes at infinite dilution in ${\text{H}}_2\text{O}$ at $25^{\circ }\text{C}$ are given:${\Lambda }_{{\text{CH}}_3\text{COONa}}^0=91.0{\text{S cm}}^2\text{/equiv}$${\Lambda }_{\text{HCl}}^0=426.2{\text{S cm}}^2\text{/equiv}$ What additional information is needed to calculate ${\Lambda }^0$ of acetic acid?
