Assuming that only oxygen evaporated, you can figure out the moles by dividing the difference in weight of the mixture by the molecular weight of the oxygen. So the answer would be (23.584-22.347)grams divided by 16.000 g/mol, or 7.7313x10^-2 moles O2.

You're right, O2 has two atoms, therefore its 32 g/mole. Thank you!
