Finding the Molar Mass
Mole to Mole Conversions
Let's say that the octane represents strawberries, and the oxygen represents bananas, and we are trying to produce a smoothie with an equal blend of both. In this example, we would use dimensional analysis to take 3.21 moles of the strawberries (A value) and multiply it by the coefficient 25 of the bananas (B value). Finally, we would divide it by the coefficient 2 of the strawberries (A value). The result is 40.1 mol, meaning that 3.21 moles of octane is equivalent to 40.1 moles of oxygen.

Theoretical Yield and Percent Yield
The percent yield, on the other hand, is calculated by placing the quantity of product gained in the actual experiment (having been altered by external factors during the experiment) over your calculated theoretical yield. You would then multiply that value by 100 in order to convert your answer into a percent.
