When 10 mL of an aqueous solution of \(F{e}^{2+}\) ions was titrated in the presence of dil. \({H}_{2}S{O}_{4}\) using diphenylamine indicator, 15 mL of 0.02 M solution of \({K}_{2}C{r}_{2}{O}_{7}\) was required to get the end point. The molarity of the solution containing \(F{e}^{2+}\) ions is \(x\times {10}^{-2}M\) . The value of x is____ (Nearest integer)
