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 NaX2COX3.


Why are they asking about the mass of oxygen? Does this refer to OX2? Shouldn't it be the mass of ozone, OX3, present in 10.6 grams of NaX2COX3, 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 NaX2COX3"?
