Chemical Equilibrium

At \(700 \mathrm{~K}\), the Equilibrium constant value for the formation of \(\mathrm{HI}\) from \(\mathrm{H}_2\) and \(\mathrm{I}_2\) is 49.0 .
0.7 mole of \(\mathrm{HI}(\mathrm{g})\) is present at equilibrium. What will be the concentrations of \(\mathrm{H}_2\) and \(\mathrm{I}_2\) gases if we initially started with \(\mathrm{HI}(\mathrm{g})\) and allowed the reaction to reach equilibrium at the same temperature?
