In this question, we're determining the molar mass of a gas given a few different information about it, including the volume, temperature, and pressure.
00:11
So obviously this is going to be an ideal gas law problem where i can just use the ideal gas law.
00:20
Okay, so we're attempting to find the molar mass.
00:25
So the first thing we should do is find the number of moles that was used, right? so we can say that n is equal to pv over r2.
00:33
T.
00:35
Then we can just fill in the values it gives us.
00:36
For pressure, it gives us 753 millimeters of mercury.
00:44
The volume, if we convert to liters, it's 117 milliliters or 0 .117 liters.
00:53
All right, so with r.
00:55
We have to use one of the r constants that uses millimeters of mercury.
00:59
So what we're going to use is 62 .363...
