Ok I'm really confused on the question I asked how many CO2 molecules can be made with 0.500 mol of oxygen atoms. Please help with setting this up

Answer 1

I looked below at my first response and your follow up. What you've REALLY asked is "Will you work it for me?" and the answer is no but I can rephrase what I wrote. If you still don't understand, explain very explicitly what you don't understand and we can go from there.
You have 1/2 mole O atoms. It takes two O atoms to make 1 molecule of CO2. So (1/2)/2 = 0.25 moles CO2 can be prepared. There are 6.022E23 molecules in 1 mole so how many are in 0.25 moles? Don't confuse the word "mole" with the word "molecules."

Answer 2

I don't want the answer. Do I have to account for the molar mass of CO2 and O2.
