Chemistry Chemistry: Molecular vs. Atomic Iodine

AI Thread Summary
Molecular iodine (I2) consists of two iodine atoms, so to convert moles of I2 to moles of atomic iodine (I), one must multiply the moles of I2 by two. For instance, 0.75 moles of I2 equates to 1.5 moles of atomic iodine. This concept is fundamental in chemistry, particularly for those beginning their studies. The discussion clarifies that the question is straightforward and not a trick. Understanding the distinction between atoms and molecules is essential for accurate calculations in chemistry.

Hello,

This question is a theory question:

I have calculated the moles of molecular iodine in a problem (I2) and the next question asks to calculate the moles of atomic iodine. Do I just multiply the number I have by two (as iodine is a diatomic molecule) or is it a "trick" question and the moles are the same.

Thanks for any help you can give me!

It's not a trick question. I is an atom and I2 is a molecule.
 
So if I have 0.75 mol of I2 then I have 1.5 mol of I?

Thanks!
 
Yes.

I assume you are just starting your chemistry education and this is one of the first assignments, not some fancy advanced problem.
 
Thanks so much!

It's actually just a small part of a larger question in a lab report but I just needed to know the theory behind the question as I was drawing a blank. The question I asked is just an example...not the actual question as I didn't want anybody to actually do the question for me (I do want to learn ;) )

Thanks for the help!
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
