I think theres a few methods to do it, but this is probably the most efficient.

Physician has prescribed 2.5% of 500ml

Actual amount of Aminosyn in this prescription is

500*0.025 = 12.5ml of Aminosin

Therefore you need to ensure when you pour your solution of the 8.5% Aminosyn, it has 12.5 ml of Aminosyn.

To work out how much 8.5% Aminosyn you should pour, you must think of the 12.5ml as 8.5%

Therefore 1% = 12.5/8.5 = 1.470588

Therefore the amount of 8.5% solution you need to pour is 100 * 1.470588 = 147.1ml

Then make up the rest (352.9ml) by adding distilled water. You now have 500ml of 2.5% aminosyn.
