PROBLEM 82P

A scuba diver breathing normal air descends to 100 m of depth, where the total pressure is 11 atm. What is the partial pressure of oxygen that the diver experiences at this depth? Is the diver in danger of experiencing oxygen toxicity?

Solution 82P

Here, we are going to calculate the partial pressure of oxygen that the diver experiences at this depth.

Step 1:

Given that, the scuba diver is breathing normal. So the percentage of oxygen in air is 21% which is fixed.

Partial pressure of a component can be calculated by using the following formula.

Partial Pressure of a component : x Total pressure

Step 2:

Partial Pressure of a Oxygen : x 11 atm = 2.31 atm

The partial pressure of oxygen that the diver experiences at this depth is 2.31 atm.
