So in this question, we're told that we have these three gases in a container.
00:05
And by percent mole, which that makes this question a whole lot easier, we have 4 .5 percent, h2s, 3 .0 percent, co2.
00:17
And the rest is n2.
00:18
So subtracting from 100 minus 4 .5, minus 3 percent, we have 92 .5 percent.
00:26
And so this is where the total, pressure here is 46 atmospheres.
00:34
And so we need to remember that the partial pressure of gas, i'll just say generically x, the partial pressure of a gas x is equal to the total pressure times its mole fraction.
00:49
So basically the percentage divided by 100.
00:53
So for instance, in the case of h2s, the partial pressure is going to be equal to the total pressure, 46, times 0 .045...
