The correct answer is

Three vessels \((A, B, C)\) contain \(\mathrm{H}_2 \mathrm{O}_2\) solution. In vessel \(A, 500 \mathrm{~mL}\) of \(10 \mathrm{vol} \mathrm{H}_2 \mathrm{O}_2\) is present. \(100 \mathrm{~mL}\) of \(30 \mathrm{vol} \mathrm{H}_2 \mathrm{O}_2\) is present in vessel \(B\). Vessel \(C\) is filled with \(250 \mathrm{~mL}\) of \(2 \mathrm{M} \mathrm{H}_2 \mathrm{O}_2\). The weight (in \(\mathrm{g}\) ) of \(\mathrm{H}_2 \mathrm{O}_2\) present in these vessels follows the order
