Hi I need help finishing a review lab report ( I don't know why I'm doing this topic, I remember doing atmospheric pressure in 9th or 10th grade ) because I completly fell asleep at arround 2am doing this and got to the last part. I need to go to school now and will print it out at school. I'll probably do the part I didnt do at lunch of something like that and need as much help as possible

the question :

4. Discuss the implications of the partial pressure of Oxygen at the altitudes and the implications for human activities/physiology. In particular, compare your chances of climbing to the top of the four mountains.

my data :

2. Estimates
i. Mt Everest ( 8849 m ) estimates at 275 mm. Hg because at 7628 meters, the atmospheric pressure is 282 and at 9153 the pressure is at 226 so a number in between that lying more towards 282 is 275.
ii. Mt McKinley ( 6194 m ) estimates at 351 mm. Hg because at 6102 meters, the pressure is 349.5 mm. Hg which is really close to 6194. 351 is also really close to 349.5 and seems likewise to be true.
iii. Mt Blanc ( 4807 m ) estimates at 413 mm. Hg because there is 1500 meters between 429 and 350 mm. Hg and so 429 – 16 is 413.
iv. Mt. Kosciusko ( 2028 m ) estimates at 595 mm. Hg because between 1829 meters ( 610 mm ) and 2134 meters ( 587 mm ) there is 300 meters of difference ( 23 mm ) so 610 – 2/3 of 23 is 595.
v. Cruising Altitude of 747 ( 11 000m ) estimates at 162 mm Hg because 10 000m is around 182 mm and 12 000m is around 142 mm so 182 – 142 is 40 and 40 divided by 2 is 20. 182 – 20 is 162.

3. Partial Pressure Of Oxygen

i. 0.21 times 275 is 57.75. The amount of oxygen at Mt Everest is 57.8 mm Hg.
ii. 0.21 times 351 is 73.71. The amount of oxygen at Mt McKinley is 73.7 mm Hg.
iii. 0.21 times 413 is 86.73. The amount of oxygen at Mt Blanc is 86.7 mm Hg.
iv. 0.21 times 595 is 124.95. The amount of oxygen at Mt Kosciusko is 125 mm Hg.
v. 0.21 times 162 is 34.02. The amount of oxygen at 11 000m is 34 mm Hg.

All I need is just a little bit of help so that I can speed up the process and finish it at lunch.

thanks.

Why is your mount everest closer to 282 than 226? 8849m is closer to 9153m than it is to 7628m. It should be around 230-233 mm hg
im not really sure about my answer but i think you could say that from your data in part three you can conclude that the higher the altitude gets the lower the oxygen pressure is. If the oxygen pressure is low there is most likely less oxygen in the atmosphere. this is because as you get closer to the higher atmosphere there is less and less oxygen molecules present. actually there is less of everything.
edit: i hate biology and im a chemE major so be careful if you even use this

Why would you measure pressure in mm Hg in the first place?
makes him look smarter by having mm Hg
my chem lab's digital barometer is in in. Hg when we were doing gasometric analysis of a compound i looked at it and was like what the **** who puts this **** in inches? thank god there was a conversion factor on there cause i really didnt feel like doing extra work
