Hello, in this question we are given that is the volume of octanol.
00:08
It is given as 10 ml and the volume of that is of the water it is given 50 ml.
00:22
And we need to find out the value of the k -o -w and k -o -c.
00:32
That is a partition coefficient value.
00:37
So, now let us find out the moles dissolved in the octanol.
00:44
So we know that, that is, moles is equal to molarity multiply by volume.
00:55
So that is for the octanol, moles for octanol, the concentration it is, that is, 0 .166.
01:07
Multiply by volume it is given that is 10.
01:10
So this will become 1 .66 m moles it is given here.
01:19
Now the moles of water.
01:29
So we can just subtract this 2 minus 1 .66 and therefore we will have 0 .34 m moles are there.
01:43
Now the concentration of the compound in water.
01:47
Is equal to moles in water divided by volume...
