Hello.
00:03
So first for this question we need to find the pressure when the gas is ideal.
00:08
We're using the ideal gas equation pv equals nrt.
00:14
The pressure is going to be nrt over v.
00:23
The number of moles was given us one.
00:27
Because the volume is in latest our r was going to be 0 .0821.
00:34
Our temperature is going to be 273.
00:42
Our volume is 5 liters.
00:46
So the pressure when the gas is ideal is 4 .40.
00:56
And that is in atmosphere, so it's here.
01:00
So now we're going to look for the pressure when the gas is real.
01:05
For real gases, the equation is going to be n squared over v squared.
01:16
So, b minus nb, so a and b are constants.
01:26
Okay, and for chlorine, the value of a is 6 .5, and the value of b is 0 .056.
01:41
So they can do the substitution here.
01:46
You have p plus a is 6 .5.
01:53
The number of most is 1.
01:55
So one's one's is still 1 so that and then says that at a v volume is 5 so v squared is 25 you got v minus number of modes is 1 here b is what 0 .0 5 622 uh...
02:16
Uh.....
