At high temperatures, iodine molecules can dissociate into iodine atoms. For the reaction ${\mathrm{I}}_2(\mathrm{g})?2\mathrm{l}(\mathrm{g})$ $\mathrm{Kc}=1.27\times 10^{?4}$ at $900^{?}\mathrm{C}.\mathrm{A}60.5\mathrm{g}$ sample of ${\mathrm{I}}_2$ is placed in a $1.00\mathrm{L}$ vessel and heated to $900^{?}\mathrm{C}$. What will be the molar concentration of iodine atoms, $[1?]$, in the vessel when the system comes to equilibrium?
