Problem 74P
PROBLEM 74P
A gas mixture contains each gas at the indicated partial pressure.
CO2 |
422 mm Hg |
Ar |
102 mm Hg |
O2 |
165 mm Hg |
H2 |
52 mm Hg |
What is the total pressure of the mixture?
Step-by-Step Solution:
Step 1 of 3
Solution 74P
The partial pressure of helium is 185 Torr.
This problem involves Dalton's Law of Partial Pressures.
For your problem, we can write this as
Ptotal=PCO₂+PAr+PO₂+PHe
745 Torr = 135 Torr + 234 Torr + 191 Torr + PHe = 560 Torr + PHe
PHe = 745 Torr – 560 Torr = 185 Torr
