Technically, none because you ALSO need S. :-).
You have 1.2 x 10^22 atoms of O. How many moles is that? Since there are 6.022 x 10^23 atoms in a mole, we must have
1.2 x 10^22/6.02 x 10^22 = about 0.02 moles O. How many moles S must we have? That will be 1/3 x 0.02 = 0.0067
Grams SO3 in 0.0067 moles SO3 is moles x molar mass or about 0.53 grams. You should go through, check all of my work, and use atomic masses and molar masses that you pick from the periodic table.
Hi, I am stop on a question that I need to use conversions for. Could someone explain to me how to do this?
How many grams of SO3 could be formed from 1.2 x 10^22 atoms of O?

My teacher taught me any of that o.o
Then you didn't need any of this? If not, wasted your time and mine.
