Question

If the partial pressure of oxygen in air at 1.0 atm is 160 mm
Hg, what is the partial pressure on the summit of Mt.
Whitney, where atmospheric pressure is 440 mm Hg?
Assume that the percent oxygen is the same.
Patients suffering from respiratory disorders are often
treated in oxygen tents in which the atmosphere is
enriched in oxygen. What is the partial pressure of O2 in
an oxygen tent consisting of 45% O2 for an atmospheric
pressure of 753 mm Hg? PLEASE HELP! I NEED THIS DUE TOMORROW. THANKS GUYS! will appreciate it. (:

Answer 1

@Callisto please help. :"(

Answer 2

I'm sorry but I haven't learnt it :(

Answer 3

the pressure at high elevation is different than sea level, but the percentages are the same. At sea level, the "normal" atmospheric pressure should be 760mm. 160mm of that pressure comes from the O2. At high elevations, the total pressure is down to 440, but the percentage of O2 has to be the same. Find the percent O2 at sea level, and use that to find the partial pressure of the O2 at elevation.

Answer 4

I get 92.6mm Hg

Answer 5

thankyou @JFraser :)
