using this formula CIVI=C2V2

(.12)(50)=(.80)(X) 1.2X50/.8 = 7.5 -50= 42.5

Simple Solution by: ChRxis

D --- x Q H

Using this formula, you can easily figure out the amount of each ingredient.

D = stg you desire, H = stg you have, Q = qty

12 ---- x 50 80

7.5ml of the 80%, then the remainder would be diluent...42.5ml

You can also use an alligation to solve this problem, although you will automatically get the equation above in the upper right hand corner of your alligation. So why not just use what we did first?
