inorganic chemistry - What is the mass of ozone present in 10.6 g of Na2CO3?



I got a question in my textbook asking for the mass of oxygen present in 10.6 grams of $\ce{Na2CO3}$.


Why are they asking about the mass of oxygen? Does this refer to $\ce{O2}$? Shouldn't it be the mass of ozone, $\ce{O3}$, present in 10.6 grams of $\ce{Na2CO3}$, since the formula of sodium carbonate contains three atoms of oxygen in its formula unit?


Would it make a difference if the question read "calculate the mass of ozone present in 10.6 grams of $\ce{Na2CO3}$"?
