How many moles of oxygen gas react to yield 0.100 mol of water?

Question:

How many moles of oxygen gas react to yield 0.100 mol of water? The reaction is:

C5 H12 (g) + 8O2 (g) → 5CO2 (g) + 6H2 O(g)

Stoichiometry:

Stoichiometry is a series of mathematical calculations that predicts how much of one substance is needed or produced based on an initial amount of another substance. The reaction in question is a hydrocarbon combustion reaction. In complete combustion reactions, carbon dioxide and water are always produced.
