I have been given a worksheet with lots of dimensional analysis. It's primarily converting grams to moles and moles to particles. However, one question asks for the moles of a bolded atom. The compound I am dealing with is NH₄OH, and the "H" in the hydroxide is bolded. The amount of moles is 5.75, so I would like to know, is my answer: 5.75 moles of hydrogen or 28.8 moles of hydrogen? I would assume it's 28.8 moles of hydrgoen because the only difference between the hydrogen in the ammonium and the hydrogen in the hydroxide is the amount and presence of the second element. However, I am not sure about this and would appreciate aid.

Question is ambiguous. I would say there are 5.75 moles of THIS particular H (not every atom in a molecule is identical, even if they are indistinguishable after being separated). But the choice of the molecules is rather lousy, as existence of NH₄OH is sometimes questioned (at best: even if it exist, it can't be isolated).
