Chemistry: Molecular vs. Atomic Iodine

Click For Summary

Discussion Overview

The discussion revolves around the theoretical understanding of the relationship between molecular iodine (I2) and atomic iodine (I), specifically in the context of calculating moles for a chemistry problem. The scope includes conceptual clarification related to basic chemistry principles.

Discussion Character

  • Conceptual clarification

Main Points Raised

  • One participant questions whether the moles of atomic iodine can be derived by simply multiplying the moles of molecular iodine by two, given that iodine is a diatomic molecule.
  • Another participant asserts that it is not a trick question, clarifying the distinction between an atom (I) and a molecule (I2).
  • A participant confirms that if there are 0.75 moles of I2, then there would be 1.5 moles of I.
  • One participant assumes the original poster is new to chemistry, suggesting that the question is basic rather than advanced.
  • The original poster expresses a desire to understand the theoretical basis behind the question, indicating that they are not seeking direct answers to their assignment.

Areas of Agreement / Disagreement

Participants generally agree on the relationship between moles of molecular and atomic iodine, with no significant disagreement noted in the responses.

Contextual Notes

Participants assume a foundational understanding of chemistry concepts, but there may be limitations in the original poster's grasp of the underlying theory.

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!
