Since H2O=2H+ 1/2 O2
so 1 mole of h2o forms 2 mol h and 1/2 mol O
hence 36ml H2O= 2mol 
and 2mol h2o forms 1 mol O and 4 mole H
so 16ml O and 4 ml H

1 mole H2O = 18 ml
Therefore , 36 ml H2O = 2 mole
Now 1 mole H2O contains 2 mole H and 1mole O
Therefore 2 mole H2O has 4 mole H and 2 mole O
 
Oxygen and hydogen both exist as a diatomic molecule. Therefore ,
No of moles of H2 = 2
And no of moles of O2 is = 1
Total volume = 36ml
Volume of H2 and O2 are in the ratio 2:1
Therefore volume of H2 = 24 ml and
Volume of O2 = 12ml
