Okay, that part is starting to make sense. Got that, atoms vs. weight, okay. And the weight is based on how many protons/neutrons actually make up the atom of the element.
BUT: you said the mole of how much reacted would be how much I measured (saying 3.00grams of iodine) divided by it's molecular weight (126.9045 for iodine). BUT Iodine crystals are I2 - so is that 3.00/126.9045 or 3.00/253.809?
