So for this problem, we're given this reaction mechanism, and i just wrote that out just as we're given it.
00:07
We're told we have a 94 % yield for each step, and it's asking how much hno3 can we produce from 5 kilograms of ammonia.
00:16
So i went ahead and wrote out the molar masses that we're going to need, and now we're ready to start this problem.
00:22
So we just have to basically go through all of these steps and solve them individually and use the answers we get from the previous.
00:31
Step to start for our next step.
00:34
So let's just start with the very first step of the reaction.
00:37
We know we have five kilograms of ammonia.
00:40
So let's do five kilograms.
00:43
Actually, let's convert that to grams, 5 ,000 grams of ammonia times a mole ratio of four times the molar mass, actually, 17 grams per moles.
00:59
17 grams is a mole.
01:04
Now we do the mole ratio.
01:06
I have four moles.
01:11
To, we want our no, so two four moles of no.
01:16
So that's the same.
01:18
And now we're going to calculate how many moles that is.
01:22
That's 5 ,000 divided by 17, which gives us 294 moles of no times...
