Someone asked the question "What is the mass of ozone present in 10.6 g of Na2CO3?". On the user page of the OP, it says "a typical ninth grader". Shouldn't a ninth grader by able to ask a question like that? It is a naive question, and it shows that the English language does not distinguish between atom types and elements. In this case, oxygen might refer to elemental oxygen ($\ce{O2}$ molecules at STP) or to oxygen atoms.
I for one would like to encourage beginners to ask questions like this on our site. I wonder if the StackExchange Chemistry community agrees with the statement "there are no stupid questions". This question might have arisen from a homework question, but it is a conceptual question showing that the OP was wondering about something. The misconception is subtle enough that I don't think you can google yourself out of it. Knowing the answer to the homework question would enable you to correctly answer more questions like this, but would not get at the concept of elemental composition like the answers posted.
I nominated the question for reopening, but unless the -5 vote on the question changes, it's not going to happen. I feel that just for preserving Ivan hilarious one-liner ("There is no arrow in sparrow"), it would be great to save this question from deletion.
