The molar conductivity vs $\sqrt{C}$ curve for $\text{Na}_2\text{SO}_4$, $\text{H}_2\text{SO}_4$, and $\text{NH}_4\text{OH}$ are shown below in random order.
Identify the curve that corresponds to $\text{Na}_2\text{SO}_4$, $\text{H}_2\text{SO}_4$, and $\text{NH}_4\text{OH}$. Justify your answer.

The molar conductivity ($\Lambda_m$) of a dilute solution of methanoic acid is $34\cdot1\text{ S cm}^2/\text{mol}$. Calculate its degree of dissociation.
(Given $\lambda^0(\text{H}^+) = 349\cdot6\text{ S cm}^2/\text{mol}$ and $\lambda^0(\text{HCOO}^-) = 54\cdot6\text{ S cm}^2/\text{mol}$)
