50% alcohol Proof ÷ 2 = % alcohol
In the United States, the "proof" descriptor for a bottle of liquor is defined as twice the percentage of alcohol by volume. Thus, a bottle labeled as "100 proof" will consist of 50% alcohol-content.
About 15. edit: Depend on where you are, in some counties are between 15-23 drinks, Here in Chile the standard is 8 (pubs, clubs, etc) but if you want something soft (house parties) It can last more, but still the average is 8 up to 10 no more than that.
the proof is used to tell you how much alcohol is in it. 100 proof is about 50% alcohol so jsut divide the proof by 2 the higer the proof the more alcohol
It's a 100 proof alcohol, and 50% alcohol content.
50% alcohol Proof ÷ 2 = % alcohol
One half of the proof is the percentage. 100 proof alcohol is 50% or half alcohol.
Alcohol is measured in proof. 100% proof whiskey is 50% alcohol. Everclear is 95% alcohol.
They sell an 80 proof(40% alcohol) and a 100 proof(50% alcohol).
100 proof alcohol is 50% alcohol and 50% distilled H20. The weight of alcohol is 7 lbs per gallon and the weight of distilled water is 8.34 pounds per gallon. if you mix them 50/50 you should have a final weight of 4.17 + 3.5 = 7.67 pounds:)
Assuming it is 90% by volume isopropyl alcohol, then 70 ml of rubbing alcohol would contain 63 mls of isopropyl alcohol.
Alcohol proof is double the actual percentage of alcohol. 100 proof is 50% alcohol, 80 proof is 40%, and 65 proof is 32.5%
