So, everyone, so according to the questions and the question says over here, as a celubility, according to the first one, as a celubility, we can write like this way, the celibility of a benzoic acid.
00:15
When we are talking about the celibility of what, benzoyic acid in where, in water, at what temperature at 0 degrees celsius is how much we are getting 1 .7 gram divided by, so what would be happen in 100 amyl? so for the 100 amyl, it will 0 .17 gram of what benzoyic acid would remain in the 100 amel of water at the 0 degree celsius.
00:45
That's what we have to return.
00:46
So it will be benzoic acid, benzoic acid would remain, it would remain, how much it would remain in 100 amyl of water at 0 degree celsius.
01:09
We need to calculate over here, this thing only.
01:13
And along with that, we need to calculate the benzoic acid cerebral in methanol, but only slightly cerebral in water.
01:20
How would that recrystallite benzoic acid use using to this solvent? so that real crystallization process is actually little lengthy that we need to calculate.
01:30
So that is the third part...
