Problem 93 says to consider the three flasks in the diagram shown here.
00:05
Assuming the connecting tubes have negligible volume, what is the partial pressure of each gas and the total pressure after all the stop clocks are opened? so for each gas, what we can do is, like the last problem, we can use the relationship between pressure and volume of the gas to use this p1 v1, p2, v2, or initial.
00:33
Final equation.
00:36
Basically what this says is that the, um, when pressure and volume of the initial, uh, conditions are multiplied, they would equal, uh, pressure and volume added together, or, um, pressure and volume multiplied together of the final condition, because pressure and volume are, uh, inversely correlated.
01:02
So what we can do is, because the problem says that the tubing here is negligible, once the stopcocks are open, the total volume of the system would be 4 liters.
01:17
That means that for helium here, the initial pressure is 200 tor.
01:25
The initial volume is 1 liter, and we can solve for the final pressure by plugging in this 4 -liter volume once the stopcocks are open.
01:40
So in solving for p2 here, we get 50 tor for neon, which i'll color in green here.
01:58
The pressure is given in atmospheres, and to keep things consistent, i'm just going to convert to tor.
02:12
We know that the initial volume of this neon flask is one liter.
02:18
And then again, once the stop clocks are all opened, we know that...
