Explanation / Answer

2 C8H18   + 25 O2    ---------------> 16 CO2 +   18 H2O

    2                 25                                   16              18

0.300           0.650

here limiting reagent is O2.

25 mol O2   -------------> 18 mol H2O

0.650 mol O2   -------------> ??

moles of H2O formed = 0.650 x 18 / 25 = 0.468

moles of water produced = 0.468 mol
