How to Find the Empirical Formula of C6H12O6
Показать описание
When given a molecular formula, look at the subscripts on all the different elements.
(If an element does not have a subscript, it is 1. For example, H2O has two hydrogens and one oxygen).
If you can divide ALL the subscripts by one number and still be left with all whole numbers, do that division. You are finding the greatest common factor (GCF).
The empirical formula is the formula with your subscripts as reduced as possible.
Note: There is not necessarily a real molecule containing the number of atoms shown in the empirical formula. It only shows the ratios of the atoms relative to each other.
