Expert Answer:

Moles space of space straight H subscript 2 straight O equals space 36 over 18 equals 2 space moles
2 straight H subscript 2 straight O rightwards arrow with Electrolyisis on top 2 straight H subscript 2 space plus straight O subscript 2

According space to space stoichiometry comma
2 space moles space of space straight H subscript 2 straight O space space gives space 3 space moles space of space space gas space left parenthesis straight H subscript 2 plus straight O subscript 2 right parenthesis

At space STP comma space 1 space mole space of space gas space occupies equals space 22.4 space straight L
So comma space space 3 space moles space of space gas space will space occupy equals space 3 cross times 22.4
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 67.2 space straight L
