In this question we have given three gases, helium, neon and argon.
00:14
Number of moles for the helium is 1 .75.
00:18
For the neon it is 2 .45 and for the argon it is 1 .10.
00:25
And the total pressure due to these gases is equals to 285 kilo -pastcal.
00:40
And we need to calculate partial pressure of helium, partial pressure of neon and partial pressure of argon.
00:54
So let's start solving it.
00:59
Total number of moles in the container will be number of moles of helium plus number of moles of neon plus number of moles of argon.
01:16
That is equals to 1 .75 plus 2 .45 .5.
01:21
Plus 1 .10 that means this will be 5 .3 moles.
01:33
We know the formula for calculating the mole fraction.
01:38
Mole fraction of helium will be equals to 1 .75 that is number of moles of helium divided by total moles which is equal to 0 .53...
