Well, 1/4 of the cc's in the vial.
20 mcg is about the size of a fly crap. The total contents are MUCH more than 20 mcg, but 20 mcg of active ingredient are dissolved in enough liquid to allow accurate dosing. There should be some "strength" indication on the bottle that tells you how many micrograms of active ingredient are dissolved in 1 cc or 1 mL of contents.
With that, you can figure it out yourself. Without it, we can't help. If it is not on the bottle, talk to the pharmacist, doctor, vet, whatever.
