What is percent dissociation of $\mathrm{NH}_4 \mathrm{OH}$ if molar conductance at zero concentration for $\mathrm{NH}_4 \mathrm{Cl}$, NaCl and NaOH are 130, 109 and $213 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$ respectively and molar conductivity of $0.01 \quad \mathrm{M} \quad \mathrm{NH}_4 \mathrm{OH}$ is $9.0 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$ ?
What is degree of dissociation of $\mathrm{CH}_3 \mathrm{COOH}$ if, $\wedge^{\circ}\left(\mathrm{CH}_3 \mathrm{COO}^{-}\right)=50 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$, $\wedge^{\circ}\left(\mathrm{H}^{+}\right)=350 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$ and molar conductivity of $5 \times 10^{-2} \mathrm{M} \mathrm{CH}_3 \mathrm{COOH}$ is $20 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$ ?
