The % concentration is:
( amount of alcohol ) / ( amount of entire solution )
---------------------
I can say that there are any amounts I choose
as long as the stated ratio is true, so
I will say:
Alcohol = ( say liters for units )
Water = ( say liters for units )
Alcohol + Water = liters
---------------------
% concentration of alcohol =
= 40% alcohol
