Here's why:
* Empirical Formula: An empirical formula shows the simplest whole-number ratio of atoms in a compound. Both dimethyl ether and ethanol have a 2:6:1 ratio of carbon, hydrogen, and oxygen atoms.
* Molecular Formula: The molecular formula represents the actual number of atoms of each element in a molecule. To determine the molecular formula, you'd need additional information, like the molecular weight of the compound.
