see attached pics...
the front of the bottle says "0.03% solution"
the back of the bottle say "0.3mg/ml"
it's been over a decade since i took analytical chemistry and i don't do this for a living. needless to say, i'm a bit rusty. would someone please help me understand this? it seems to me that the front and back of the bottle say different things (concentrations).
*how much bimatoprost is in that bottle?
**if i have 1mg of bimatoprost in dry form, how much water do i dissolve it in, if i want to end up with the same concentration of solution as is in that bottle?
many thanks for your assistance!

These are practically the same concentrations.
Question 2 - read Forum Rules.

If 100% is 1000mg/ml (1g/ml), and 1% is 10mg/ml, how much is 0.03%?
