What is the concentration of $[H_3O^{+}]$ ion in $mol \ L^{-1}$ of $0.001 \ M$ acetic acid $(\alpha = 0.134)$?

At $25\,^{\circ}C$,the molar conductance of a $0.1\, M$ aqueous solution of ammonium hydroxide is $9.54\, \Omega^{-1}\, cm^2\, mol^{-1}$ and at infinite dilution,its molar conductance is $238\, \Omega^{-1}\, cm^2\, mol^{-1}$. The degree of ionisation of ammonium hydroxide at the same concentration and temperature is ............ $\%$

$HCN$ is $1 \%$ ionized in its $0.2 \ M$ aqueous solution. At the same temperature,what would be its percent ionization in its $0.02 \ M$ aqueous solution?
