Okay, this is basically a pvnrt problem.
00:06
We are given chlorine gas and a specific number of moles, 0 .032, and this is going to be our n in our equation.
00:15
We have a pressure of 7 .5 times 10 to the minus 4 millimeters of mercury.
00:22
Our temperature is 19 degrees c, and we need to figure out l or the volume in liters.
00:30
However, we need r.
00:32
And the easiest r to find or to use is this one, 0 .08 -206, liters, atmospheres, mole, kelvin.
00:43
Now, if you'll notice, we have a bunch of different units than what we were given.
00:48
We need to convert our pressure from millimeters and mercury into atmospheres and our temperature from celsius into kelvin.
00:55
So i did that here.
00:58
We have 7 .5 times 10 to the minus 4 millimeters in mercury.
01:02
Now the conversion is one atmosphere is equal to 760 millimeters of mercury.
01:08
And when you do the math, it comes out to be 9 .868 times 10 to the minus 7 atmospheres.
01:15
So this is our new p.
01:19
Now to convert celsius into kelvin, we have to, sorry, this should be add, 270, to our celsius, and we'll get kelvin, in this case, 292 .15, and this is going to be our new t...
