$A$ weak monobasic acid is $10 \%$ dissociated in $0.05 \ M$ solution. What is its percentage dissociation in $0.10 \ M$ solution (in $\%$)?

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 ............ $\%$

How much water must be added to $300 \ mL$ of $0.2 \ M$ solution of $CH_3COOH$ $(K_a = 1.8 \times 10^{-5})$ for the degree of ionisation $(\alpha)$ of the acid to double (in $mL$)?

For a weak electrolyte,the degree of dissociation $\alpha$ is:

Which of the following substances,when dissolved in water,will give a solution that does not conduct electricity?

The equivalent conductance of benzoic acid is $12.8 \ ohm^{-1} \ cm^{2} \ eq^{-1}$. If the equivalent conductance of benzoate ion and $H^{+}$ ion at infinite dilution is $42 \ ohm^{-1} \ cm^{2} \ eq^{-1}$ and $288.42 \ ohm^{-1} \ cm^{2} \ eq^{-1}$ respectively,then its degree of dissociation is ............. $\%$
