100 mL of ${\mathrm{H}}_2{\mathrm{O}}_2$ solution having volume strength 11.35 V is mixed with 500 mL of given KI solution to liberate ${\mathrm{I}}_2$ gas. All the ${\mathrm{I}}_2$ gas liberated is dissolved to form 500 mL solution. 200 ml of the solution required 50 mL of  $\frac{2}{3}\mathrm{M}$ hypo solution. Calculate volume strength of remaining ${\mathrm{H}}_2{\mathrm{O}}_2$ mixture. Round off your answer to nearest integer.  $[\mathrm{S}.\mathrm{T}.\mathrm{P};{\mathrm{V}}_{\mathrm{m}}=22.7\mathrm{lit}]$
