A \[200\text{ }mL\]solution of \[{{I}_{2}}\] is divided into two unequal parts. Part I reacts with hypo solution in acidic medium and requires\[8\text{ }mL\]  of \[2\text{ }M\]hypo solution for complete neutrali sation. Part II was added with \[300\text{ }mL\]of \[0.1\,M\]\[NaOH\]solution. Residual base required \[30\text{ }mL\]of \[0.1M\]  \[{{H}_{2}}S{{O}_{4}}\] solution for complete neutralisation. The value of 20 times the initial concentration of \[{{I}_{2}}\] is _______.
