Question

calculate volume of 0.2m aqueous h2o2 solution
​

Answer 1

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)2❌24 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(68❌10)➗22.7 =29.9 gm =30 gm H2O2.
