How many moles of H2O are produced when 0.30 mole of O2 are consumed?

    It depends entirely on what the O2 reacted with. Jim Moor and Trevor H have assumed the O2 reacted with H2, but I see nothing in the question that even implies that.

    Take propane for example:

    5 O2 + C3H8 → 4 H2O + 3 CO2

    (0.30 mol O2) x (4 mol H2O / 5 mol O2) = 0.24 mol H2O

    0.30 m O2 (2 moles H2O/1mole O2) = 0.60 moles H2O

    Balanced equation:

     2H2(g) + O2(g) → 2H2O(g)

    1mol O2 will produce 2 mol H2O

     0.3 mol O2 will produce 0.6 mol H2O.
