How many moles of oxygen gas react to yield 0.200 mole water? C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)

Read the ratio from the balanced equation you have there: CO\(_2\) = 8 to H\(_2\)O = 6 use to convert: \[0.200molH_2O \large\cdot \frac{8 mol O_2}{6molH_2O} = ? molO_2\] The units for moles of water cancel out as you can see.
