Can a molecular formula ever be the same as an empirical formula? Give an example.

Different compounds can have the same empirical formula. For example, ethylene C 2 H 4 and propylene C 3 H 6 have the same empirical formula, CH 2. In the same manner, compounds can have the same molecular formula. For example, ethanol and dimethyl ether have the same molecular formula, C 2 H 6.

Explanation:

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
