A major component of gasoline is octane (C8H18). When liquid octane is burned in air it reacts with oxygen (O₂) gas to produce carbon dioxide gas and water vapor. Calculate the moles of octane needed to produce 0.060 mol of water. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Expert Solution
Step 1

The balanced combustion reaction of octane is as follows:

2C8H18  +  25O2    16CO2  +  18H2O

The stoichiometry of the balanced chemical reaction states that two moles of octane reacts with fifteen moles of oxygen to form sixteen moles of carbon dioxide and eighteen moles of water.
