Okay, first thing that we're going to do is figure out the number of moles in this 4 .5 grams of nitrogen gas n2.
00:08
So in one mole, we know that there are 28 .02 grams of n2.
00:13
So let's figure out this mole amount right here.
00:19
So this is going to equal 0 .162 moles.
00:22
The reason we know it's 28 .02 is because there is two n's, so each of them is 14 .01.
00:27
Now we're going to use this.
00:29
We're going to use our ideal gas law pv equals nrt.
00:32
We're going to solve for temperature.
00:34
So pv divided by nr is going to be equal to t.
00:38
All right, so let's plug some variables in.
00:39
Our pressure, 2 .97 atm.
00:43
Volume is 0 .873 liters...
