Sol. Volume strength of H2O2 = Normality × 5.6
= 1.5 × 5.6 = 8.4 V

Dear Student
We know that equivalent weight of H2O2 is 17
and strength of H2O2=Normality x Equivalent weight
= 1.5x 17 = 25.5
Since 68 grams of H2O2 produces 22.4 litres oxygen at NTP
Therefore 25.5 grams of H2O2 will produce = 22.4/68 x 25.5 = 8.4 litre of oxygen
Thus, volume strength of given H2O2 solution is 8.4
I hope this answer will help you.
Thanks & Regards
