Pharmaceutics 20 分!!!

You may use a 50ml pipette to draw 50ml of hibitane 5%w/v to a 500ml volumetric flask and up to volume.
For less accurate result, you may use measuring cylinder instead of pipette. Remember, don't use the apparatus for internal solution!!
The percentage strength is 0.5% (w/v).
Ratio strength?? 1 in 200.
P.S. You are a university student, you need to do it yourself. No one can hlep you in exam.
