$A$ weak monobasic acid is $4\%$ dissociated in $0.05 \text{ M}$ solution. What is the percent dissociation in $0.1 \text{ M}$ solution (in $\%$)?

$A$ solution of $HCl$ in water is a good conductor while gaseous hydrogen chloride is not. This is due to the reason that

The degree of dissociation in a weak electrolyte increases:

The extent of ionization increases:

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

The equivalent conductance of a $0.1 \ M$ weak acid is $100$ times less than its equivalent conductance at infinite dilution. The degree of dissociation is .....
