1. Commercial scuba divers use tanks filled with a mixture of gases known as Trimix on very long, deep dives. Trimix is composed of 70% nitrogen, 10% oxygen and 20% helium. The total pressure of the Trimix inside a certain tank at the beginning of the dive is 118.4 atm. A. What is the partial pressure of the oxygen in the tank? B. Recall that total pressure of air at sea level is about 1 atm, and that air is 20.9% oxygen. How does the partial pressure of oxygen in the tank compare to the partial pressure of oxygen in air? (is the same or different; how much lower or higher is it?)
