All the comments you have made are true. My purpose with the blog was to provide a simple example of percent composition. I felt that stating the link between the mole and empirical formulas to percent composition, though important information, was an unnecessary tangent that would weaken the focus of the blog. Also, since this was a How-To blog, I wanted to emphasis the math and logic used. Thank you for your comment.

How exactly would this apply to combustion? And, you imply that this is not related to the mole or empirical formulas by your statement, “Scientists can deduce more about chemical processes using units such as the mole and employing empirical formulas.” Yet isn’t the very process you state for determining formula weight based on molar relationships quantified by the subscripts in the formula? Isn’t this why 12.01g of carbon is multiplied by 6? Additionally, if you determine that a compound is 40% carbon, isn’t that information one means of determining empirical formulas?
