If the values of $\Lambda_{\infty}$ of $NH_4Cl$,$NaOH$ and $NaCl$ are $130$,$217$ and $109 \ ohm^{-1} \ cm^2 \ equiv^{-1}$ respectively,the $\Lambda_{\infty}$ of $NH_4OH$ in $ohm^{-1} \ cm^2 \ equiv^{-1}$ is:

At $25^o C$, the molar conductivities at infinite dilution of $NaOAc$ and $HCl$ in water are $91.0 \, S \, cm^2/mol$ and $426.2 \, S \, cm^2/mol$, respectively. Which substance's molar conductivity must be subtracted to calculate the molar conductivity of $HOAc$ at infinite dilution?

The conductivity of $0.001 \ M$ acetic acid at a certain temperature is $5.07 \times 10^{-5} \ S \ cm^{-1}$. If $\wedge_m^0$ of acetic acid at the same temperature is $390 \ S \ cm^2 \ mol^{-1}$,the dissociation constant of acetic acid at that temperature is:
