Alrighty, so our dosing has 25 milligrams per 0 .5 militers or per half militre.
00:10
So we want to know how many mil liters would we need to get 0 .25 milligrams of the drug substance.
00:19
So, and actually i need to reverse a little bit.
00:28
This is not milligrams.
00:30
This is micrograms.
00:32
So if we remember, one milligram equals a thousand micrograms.
00:48
Now that we have these two things, we know we want 0 .25 milligrams, oops, per how many milliliters? so first thing i'm going to do is turn this 25 micrograms into milligrams.
01:16
So if we have one milligram per 1 ,000 micrograms, and we want 25 micrograms, how many milligrams is that going to be? so we're going to do some cross multiplication...
