Question

What partial pressure of oxygen is a scuba diver breathing?

Answer 1

Answer:

Remember that for each 10 m of depth the pressure increases by 1 atm, but the pressure at the surface is 1 atm, so the partial pressure of oxygen in air would be 1.6 atm at 66 m (216 ft). Nitrogen narcosis can result from a diver's exposure to high partial pressures of nitrogen during her dive.
