A helium balloon takes up 4.35 liters of space. Your friend is showing off his new chemistry skills and shows you his dimensional analysis to solve for the number of moles in this balloon. He found there would be 0.91 moles in the bottle. You know, of course, that this value makes no sense. Describe how you would teach him to determine if his dimensional analysis answers "make sense" using this situation as an example.
