For the reaction, ${\mathrm{N}}_2{\mathrm{O}}_4(\mathrm{g})\rightleftharpoons 2{\mathrm{NO}}_2(\mathrm{g})$; if percentage dissociation of ${\mathrm{N}}_2{\mathrm{O}}_4$ varies as $25\%$, $50\%,75\%$ and $100\%$, then the corresponding observed vapour densities of the reaction mixture are related as
