The molar conductance of an infinitely dilute solution of ammonium chloride was found to be $185 \, \text{S cm}^{2} \, \text{mol}^{-1}$ and the ionic conductance of hydroxyl and chloride ions are $170 \, \text{S cm}^{2} \, \text{mol}^{-1}$ and $70 \, \text{S cm}^{2} \, \text{mol}^{-1}$, respectively. If molar conductance of $0.02 \, \text{M}$ solution of ammonium hydroxide is $85.5 \, \text{S cm}^{2} \, \text{mol}^{-1}$, its degree of dissociation is given by $x \times 10^{-1}$. The value of $x$ is _____ . (Nearest integer)
