Homework Help: Chemistry: Molecular vs. Atomic Iodine

  1. Oct 13, 2011 #1

    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?

    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!
