In dilution, we're changing the concentration of a solution by changing its volume.
00:06
Nevertheless, the concentrate, the amount of the solute that is dissolved in the solution does not change.
00:13
And so we can use the dilution formula, which is of the form c1 v1 equals c2 v2, where c is the concentration, v is the volume, 1 and 2 are the initial and final.
00:26
So let's say like for example c1 is the initial concentration, c2 is the final concentration, v1 is the initial volume, and v2 is the final volume.
00:40
So for this problem, we have a .969 molar concentration of kno3 solution.
00:48
So that will be our c1.
00:52
The volume of which is given to be equal to 15 ml.
00:56
So that serves as our v1...
