A solution is made by mixing \( 200 \mathrm{ml} \) of \( 0.1 \) \( \mathrm{M}-\mathrm{FeSO}_{4}, 200 \mathrm{ml} \) of \( 0.1 \mathrm{M}-\mathrm{KMnO}_{4} \) and \( 600 \mathrm{ml} \) of \( 1 \mathrm{M}_{-\mathrm{HClO}_{4}} \). A reaction occurs in which \( \mathrm{Fe}^{2+} \) and \( \mathrm{MnO}_{4}{ }^{-} \)convert to \( \mathrm{Fe}^{3+} \) and \( \mathrm{Mn}^{2+} \). If the molarity of \( \mathrm{H}^{+} \)ion in the final solution is ' \( x \) ' \( \mathrm{M} \), then the value of \( 1000 x \) is
