A sample of h202 is labelled as 10 volume its strength in gram/litre

Answer 1

Answer:

Mark it as brainliest

Yes

Explanation:

10 volume solution of H22 means that 1 litre of this is H2O2 solution will give 10 litre of oxygen at STP.2 H2O2 (l) ➡ O2(g) + H2O (l)2x24 gm 22.7L at STP68gm On the basis of above equation 22.7 litre of O2 is produced from 68 gram H2O2 at STP 10 litre of O2 at STP is produced from(68x10)/22.7 =29.9 gm =30 gm H2O2.

Therefore strength of H2O2 in 10 volume H2O2 solution = 30 gm/L = 3 % H2O2 solution.
