1. A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 × 10^4 kPa and 4.34 × 10^3 kPa, respectively. What is the total pressure of the tank? Remember that (1.0 × 10^5) + (1.0 × 10^5) = 2.0 × 10^5.
a. 3.71 × 10-^1 kPa
b. 2.04 × 10^4 kPa
c. 6.99 × 10^7 kPa
d. 1.18 × 10^4 kPa
2. At a depth of 40 m, the water pressure is 500 kPa. A diver breathing air (78% N2, 21% O2) at this depth would have what partial pressure of oxygen in his lungs?
a. 5.1 kPa
b. 105 kPa
c. 396 kPa
d. 508 kPa
