Consider the dissociation of the weak acid $\mathrm{HX}$ as given below $\mathrm{HX}(\mathrm{aq})\rightleftharpoons {\mathrm{H}}^{+}(\mathrm{aq})+{\mathrm{X}}^{-}(\mathrm{aq}),\mathrm{Ka}=1.2\times 10^{-5}$ $[{\mathrm{K}}_{\mathrm{a}}$ : dissociation constant $]$ The osmotic pressure of $0.03\mathrm{M}$ aqueous solution of $\mathrm{HX}$ at $300\mathrm{K}$ is _______ $\times 10^{-2}$ bar (nearest integer). [Given : $\mathrm{R}=0.083\mathrm{L}\mathrm{bar}{\mathrm{mol}}^{-1}{\mathrm{K}}^{-1}$]
