Hi there.
00:01
So for this problem, we are told that dry earth is 78 .1 % nitrogen.
00:08
78 .1 % of nitrogen, molecular nitrogen.
00:16
So the question is, what is the partial pressure of nitrogen when the atmospheric pressure is given? and that atmospheric pressure is equal to a value of 1 .01 times 10 to the 5 newtoms per meter square.
00:35
Now, we note that air is composed primarily of nitrogen and oxygen.
00:45
Now, if 78 .1 % of this is nitrogen, the order remaining to get, get to the 100 % is oxygen.
00:56
So the partial pressure is just the percentage that we are given for nitrogen times the atmospheric pressure because the atmospheric pressure is just the complete pressure with the nitrogen, considering a nitrogen, oxygen, and other gases.
01:21
So the pressure, the partial pressure produced by nitrogen is just simply...
