Verified Solution • 2025–26 Session moderate

The strength of 11.2 volume solution of H₂O₂ is : [Given that molar mass of H = 1 g mol–1 and O = 16 g mol^–1]

Accepted Answer

Strength means

\frac{W e i g h t}{V o l u m e}

%.

Molarity of H₂O₂ =

\frac{v o l u m e s t r e n g t h}{11.2}

=

\frac{11.2}{11.2}

= 1 M = 34 gm/lit

In 1000 ml solution 34 gm H₂O₂ present

∴

In 100 ml solution 3.4 gm H₂O₂ present.
