When$10 \mathrm{mL}$of an aqueous solution of${\mathrm{Fe}}^{2+}$ions was titrated in the presence of dil${\mathrm{H}}_2{\mathrm{SO}}_4$using diphenylamine indicator,$15 \mathrm{mL}$of$0.02 \mathrm{M}$solution of${\mathrm{K}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7$was required to get the end point. The molarity of the solution containing${\mathrm{Fe}}^{2+}$ions is$\mathrm{x}\times {10}^{-2} \mathrm{M}$. The value of$\mathrm{x}$is ______. (Nearest integer)
