Trying to figure out the correct way to calculate the alcoholic content of a mixed drink.
I am only using two liquids, one alcoholic and the other water (zero alcohol)
25.4 oz of 190 proof/95% alcohol
64 oz. of 0 proof/0% alcohol
I added the two volumes together, 89.4 oz.
I calculated the percentage of alc. liquid to total liquid = 25.4/89.4 = 28.4%.
I multiplied the above 28.4% and the proof of the alcohol = .284 x 190 = 53.96 proof or 26.98% alcohol.
So I've concluded that the resulting liquid is about 54 proof.
Have I calculated correctly? If not, what step(s) do I need to adjust?
TIA,
Steve
