Math conversion question

Ok guys, I got thru high school and tech school math, but I need help with this one.

I need to take 10 mcg of a product that comes in a liquid. Bottle says 200mcg/ML. Dropper inside bottle starts at .25ML. How much of that dropper equals 10 mcg? I know it 's not goin to be much, but need to start low and test sides. Thx in advance for help.

If you want 10mcg of a 200mcg/ml solution, you will need .05ml. In other words, one fifth of the .25 ml marked on the dropper.

Hopefully someone can confirm my math, but I'm pretty sure that is right.

This is correct. You may want to order a smaller dropper

I would lower the concentration if possible. If not, draw it with a tuberculin syringe.


Edit. The needle on a tuberculin syringe is usually removable.
