Okay, so we didn't. Chapter one problems 67. And so this is based on a multiple choice based off the cuff or the passage about the lungs. So what we're gonna do is what is the total volume of gas? Extreme region of the belongings. So the total volume we know is going to be equal to the number of How've you, Lee, Whatever you say that times the average call you of a single will be okay. So that means if we women looked at a value became take. However many we have which look at the problems for 100 times into the six, we can multiply that by the volume of each one, which is 4.2 times tend to them six micro meters cued over the number of them. So the numbers that's now and now we convert these micro meters two meters. So for one meter is 10 to the negative six micro speakers. Er sorry. It's 10 to 6 micro leaders. So now micro meters will cancel Al. But we have to keep that to make that work. And then we convert cubic meters. Two leaders over there has 1,000 leaders and one cubic meter. Now we can do this all in our calculator. At one step, we see this's 2.0 leaders. So if you look at our options, that is option C.
