In this video, we are going to do a dilution on some 12 molar hcl.
00:08
We want, so we start with 12 molar, and we want 250 milliliters of, what is it, of 2 molar.
00:24
So we have our final molarity and final volume.
00:28
This is going to be m2 and this is v2.
00:30
We have our initial molarity.
00:32
And so we're looking for our initial volume, oops, v1, initial volume v1, and since we're using milliliters on this side, it will be in units of milliliters.
00:44
So let's rearrange this equation to solve for v1.
00:47
If we divide both sides by m1, we get m2 v2 over m1, and then we could plug in...
