I know that there are 6.02 x 10^23 atoms in one mole of carbon dioxide, but I don't know. I'm just really confused right now. I've been working on my chemistry summer more

Look at it this way,

1 mol carbon dioxide (CO2) contains 1 mol of carbon atoms and 2 mols of oxygen atoms.
1 mol = 6.02 x 10^23
2 mol = X

Cross multiple the 6.02 x 10^23 by 2 and you get
1.02 X 10^24 oxygen atoms in one mole of carbon dioxide

This was the only correct answer, although the last one seems right too, but I checked somewhere else, and this one's it! Thanks! :-)

    Lol I've always sucked at chemistry, but this is one thing I get. In one molecule of carbon dioxide, there are three parts: two oxygen atoms (dioxide= "two oxygen") and one carbon atom. Therefore, 2/3 of every carbon dioxide molecule is oxygen, so 2/3 of a mole of carbon dioxide is oxygen. Multiply 6.022 x 10^23 by 2/3 and that's how many oxygen atoms are in a mole of carbon dioxide. Good luck. :)
