    (e) Dalton’s Law Challenge Question: Ordinary air contains about 78% nitrogen, 21% oxygen, and small amounts of several other gases. As a diver descends, the pressure of the air he is breathing increases by about one atm for every 10 m of depth. Oxygen may become toxic and cause convulsions if it is breathed at a pressure above 1.4 atmospheres. According to Dalton’s Law, at what depth should a SCUBA diver be concerned about oxygen toxicity if he is breathing ordinary air? Discussion Points: • Dalton’s Law states that the pressure exerted by a mixture of gases is equal to the sum of the pressures that would be exerted by the gases individually. • Since air contains about 21% oxygen, so the pressure of oxygen at the surface is about 0.21 atmosphere.…

Once you hit the surface the computer tells you how what…
