Alright, so here we have a gas mixture that has 0 .830 atmospheres of helium, 622 tor of neon, and 431 millimeters of mercury of argon.
00:24
We want to know what's the total pressure of a gas mixture in the units tor.
00:28
So to convert these into tor, we can first start with atmospheres.
00:34
So we know for helium, one atmosphere is equal to 760 tor.
00:47
So if we plug this into our calculator, 0 .830 times 760 gives us 630 .8 tor.
01:04
For argon, this one's a little bit easier.
01:12
We know that 760 millimeters of mercury equals 740.
01:19
260 tor or 1 equals 1.
01:22
You can also write it that way.
01:24
So 431 times 760 divided by 760.
01:28
It's just going to be equal to 431 tor.
01:32
And so because each of these are partial pressures, the total pressure is going to be the sum of the partial pressures.
01:39
So the total pressure of the gas mixture, we can just add all of these up.
01:48
So 622 plus 630 .8 plus 431...
