00:01
So to solve for this, we'll use this formula.
00:04
We know that the concentration of initial solution multiplied by its volume and added with another solution.
00:16
So that means concentration of the second solution multiplied by the respective volume will result to the concentration of the resulting solution.
00:28
So c3 multiplied by the respective volume will result to the concentration of the resulting solution.
00:30
The bt, which is equivalent also to the sum of v1 and v2.
00:36
Okay, so concentration of the initial solution or the first solution of the tae buffer is, concentration is one, i mean, concentration is 20x.
00:52
So that's the initial solution.
00:54
So let's try it here, 20x.
00:57
And then the volume is unknown.
01:00
Okay, so v1 is our unknown here.
01:04
And then for c2, we are to add the buffer with water.
01:11
Okay, so for the second solution, since it does not contain any tiee buffer, that means concentration will be zero.
01:23
Okay, and then for v2, we have, it is also unknown, but we'll just write it as b2...
