Molecular weight of water is 18, so there are 150/18 moles of H2O.  As there is one atom of Oxygen for each molecule of water there are 150/18 moles of Oxygen.

This is actually a math question because h2o is water so just count the molecules of oxygen in 150 grams of water. (Don't be afraid to tell me I'm wrong b/c I've never taken chemistry.

Very cool, but I doubt I will be needing it anytime soon.
