Problem 51 asks you to complete this table here for an ideal gas.
00:06
I'm noticing that part of this is cut off.
00:09
So excuse me while i fix the table just a little bit.
00:13
This bottom row here is 2 .25 liters and 10 .5 moles.
00:33
Okay.
00:33
So to complete this table, what we have to keep in mind here is that we're essentially for each of these sets of values a through d, we're plugging the information that we have into the ideal gas equation and solving for what we have to solve for.
00:56
I'll just give you the r constant here, the ideal gas constant.
01:00
Recall that it's .08206 meter atmospheres over moles times kelvin.
01:11
So because i have very little space to fill on these tables, i'll just refer to this as r, but keep in mind that's what i'm plugging in to the equation here.
01:20
So in part a to solve for volume, we know that we have a pressure of five atmospheres.
01:29
We have two moles of this gas times r, and then because we have this temperature in degrees celsius here, the standard for the ideal gas equation is to have your temperature in kelvin.
01:49
So what you'll do here is just add 273, giving us 428, and that's what we'll plug into this equation here...
