We want to synthesize 19 .0 .0 and we're asked what volume of o2 is required.
00:30
And we're given conditions of 465 liters at 988.
00:44
It already gave me this.
00:47
Squared just what volume of oh is produced by the...
00:52
I need to synthesize 19.
00:55
Moles and i'm given volume equals 465 liters.
01:09
My pressure equals 98mm mercury, the temperature equals 37 degrees kelvin.
01:26
So this will be 310 or celsius, i should say kelvin.
01:36
My r for this one is 36 point, i think it's 20, no it's not 63 .63.
01:48
I'm going to go look that up.
01:51
R for mmhg is 62 .36.
01:58
62 .36.
02:04
L .mhg over k mole.
02:13
Okay.
02:14
So let's figure out from this how many moles.
02:18
Of 02 we have.
02:24
And that will be equal to moles equals pv over rt, so n will equal 98 mmhg times 465 liters divided by 62 .36 l mhg over k -mole times 310 kelvin.
03:10
I'm going to put my k down there because i don't have room.
03:15
Let me write this down.
03:16
90 times 465 divided by 62 .36 divided by 310.
03:23
Here i get 23 .7775 moles of 02.
03:36
Now let's figure out how many moles we need...
