A heliox deep-sea diving mixture contains 2.0 g of oxygen to every 98.0 g of helium. What is the partial pressure of oxygen when this mixture is delivered at a total pressure of 8.2 atm?
The partial pressure is proportional to the mole fraction....
Thus, we determine each mole fraction separately.
The diver is at a significant depth, and if he or she had been breathing in nitrogen, such as from a typical air mix, they would probably have developed nitrogen narcosis.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
