12. An airplane is pressurized with air to 650. mmHg. a. If air is 21% oxygen, what is the partial pressure of oxygen on the plane? 0.21 x 650 = 136.5 mmHg - Partial Pressure of O2 b. If the partial pressure of oxygen drops below 100. mmHg, passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped?

Step 1
So, if the partial pressure of oxygen drops below 100 mmHg, we can set up the following equation to find the total cabin pressure: 0.21 * X = 100 mmHg Show more…

An airplane is pressurized with air to $650 .$ mmHg. (8.6) a. If air is $21 \%$ oxygen, what is the partial pressure of oxygen on the plane? b. If the partial pressure of oxygen drops below $100 .$ mmHg. passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped?
Gases
Partial Pressures (Dalton's Law)
The pressure outside a jet plane flying at high altitude falls considerably below atmospheric pressure at sea level. The air inside the cabin must therefore be pressurized to protect the passengers. What is the pressure (in atmosphere) in the cabin if the barometer reading is $688 \mathrm{~mm}$ of $\mathrm{Hg}$ ? (a) $0.905 \mathrm{~atm}$ (b) $6.88$ atm (c) $9.05 \mathrm{~atm}$ (d) data, insufficient

(a) Given that air is $21 \%$ oxygen, find the minimum atmospheric pressure that gives a relatively safe partial pressure of oxygen of 0.16 atm. (b) What is the minimum pressure that gives a partial pressure of oxygen above the quickly fatal level of 0.06 atm? (c) The air pressure at the summit of Mount Everest (8848 m) is 0.334 atm. Why have a few people climbed it without oxygen, while some who have tried, even though they had trained at high elevation, had to turn back?
