A lot of this problem teaches us how to manipulate the equations for pressure that we know in order to find the height of a specific atmospheric component that we need to investigate.
00:14
And the first way that we're going to do this is essentially combine multiple equations that we know.
00:21
So the first thing that we should note is the ideal gas law.
00:24
This is a very prominent equation in gaseous chemistry.
00:28
You know that pv equals n r t, we sometimes say this is pvnerd, p is pressure, v is volume, n is moles, r is a gas constant, and t is our temperature.
00:42
However, we also have another equation involving pressure.
00:47
You say that p m is equivalent to row times r t.
00:50
Again, p is pressure, m is mass, row is a greek letter, and we use this to denote density.
00:58
R is again, p is pressure, and is mass, a constant and t is our temperature.
01:03
There is also another equation for pressure.
01:06
We know that p is equivalent to h times row times g...
