Hey everyone, so in this question what is the partial pressure of oxygen and nitrogen in air so the concept in this question we use the relation between partial pressure that is equal to mole fraction multiply by total pressure so this is the relation we use so partial pressure of any gas that is equal to mole fraction of that particular gas multiply by total pressure so here partial pressure of oxygen that is equal to mole fraction of oxygen multiply by total pressure.
00:32
And similarly, partial pressure of nitrogen that is equal to mal fraction of nitrogen multiplied by total pressure.
00:39
So let us see the data given in the question.
00:41
So we are given percent of nitrogen, 78 percent of oxygen, 21 percent and percent of other gases is approximately 1 percent.
00:49
So this data is given.
00:51
Also, total pressure that is 680 millimeter mercury.
00:56
So this information is also given in the question.
00:59
So, as you can see, we have to find first about the mole fraction of oxygen...
