Okay, so it's about the production of the urea.
00:04
So it says, right, you want to produce one tons of the urea.
00:08
So one tonne is about 1 ,000 kilograms.
00:15
So we can convert that.
00:16
It's about 1 times 10 to 6 grams of the uranium urea, right? and if we look at the structure, the urium has two ammonia and co.
00:32
So it says, right, you're going to use the ammonia to produce the urea.
00:41
And looking at this reaction, yes, we are not able to just, right, even though we don't know the reaction.
00:49
What is the reaction you'll find, right? the urea has two nitrogen, and all the nitrogen will be provided by the ammonia.
00:57
So that means, right, one mores of the urea should be corresponding to two more ammonia.
01:03
So in this case, what we can do is first we can calculate the mores of the urea that's equal to the mass of the urea over the more mass.
01:17
So the mass here is we want to produce 1 tons of urea.
01:22
So it's 1 times 10 to 6 over the more mass.
01:26
The more mass here is about, so 16 plus times 2 plus the co 12, 12, plus 16 so that's about 60 so it's 1 times 10 to 6 over 60 so that's equal to so we probably can just write here it's 1 over 60 times 10 to 6 and looking at here right as i mentioned that one more of urea corresponds to more ammonia so that means the more ammonia should be equal to two more to the urea so that's about two times one over 60 times 10 to 9 to 6 so that becomes 1 over 30 times 10 to 6 more and in this case it says right with one know the volume and it's at a pressure 150 atm so in this case we're going to use pv equals to nr t so in that case, the pv equals to nrt.
03:19
So we need to know the volume here...
