Molecules vs Formula Units
Can anyone explain to me what the difference is between molecules and formula units, if any? I have noticed in the book that it will sometimes ask for the formula units of a compound or element and I don't necessarily know what they are! Any help would be greatly appreciated :)

Re: Molecules vs Formula Units
From what I remember, molecules are the molecular formula and the formula units are empirical formula (the base amount of each element necessary to produce a molecule).

Re: Molecules vs Formula Units
Hi,
Molecules are covalently bonded atoms and Formula Units refer to only ionic compounds. When you are asked to find the empirical formula of a compound, but it is an ionic compound, you will likely be asked it's formula units instead of the amount of each atom in the molecule.
Hope this helps!

Re: Molecules vs Formula Units
I agree with what people have said earlier. I think it is also important to note that when using Avogadro's number to make conversions, atoms, molecules, and formula units are basically treated in a similar fashion.

Re: Molecules vs Formula Units
I agree with the others, I was initially confused before as well as the textbook did not specify that it was either one and not both. But yep molecules would be for covalently bonded and formula units for ionic bonds. However, I don't think we need to know exactly which one we are finding yet, as we are just starting to work on chemical bonds.

Molecules would be for covalent bonds and formula units would be for ionic bonds!
Re: Molecules vs Formula Units
Molecules are covalently bonded atoms while formula units are the empirical formula for ionic compounds.

Re: Molecules vs Formula Units
In terms of Avogadro's number, 6.022 * 10^23 can refer to atoms, molecules, or formula units. Molecules refer to covalently bonded compounds whereas formula units refer to ionic compounds.

Re: Molecules vs Formula Units
Molecules refer to atoms with covalent bonds in between them, and formula units are atoms that have ionic bonds.

Re: Molecules vs Formula Units
Hi! molecules=molecular formula and the formula units=empirical formula
