Chapter 12, Problem 100TE

Some bottled water is now advertised as containing extra quantities of "Vitamin O," which is a marketing gimmick for selling oxygen, ${\text{O}}_{\text{2}}$. Might this bottled water actually contain extra quantities of oxygen, ${\text{O}}_{\text{2}}$? How much more might it be than one might find in regular bottled water? How might the amount of oxygen we absorb through our lungs compare to that which we might absorb through our stomach—say, after burping?
