The strongest alcoholic drinks can have alcohol content ranging from 40% to over 90%. However, many commercially available strong alcoholic beverages like spirits typically range from 40-50% alcohol by volume (ABV).
2.8 percent alcohol
Because the concentration of alcohol is lower; you pay the alcohol not the water.
This is a solution containg 60 percent isopropyl alcohol; can be used as rubbing alcohol.
There is no way to calculate that with the information provided. We need to know the volume of each.
Add 5% water
The Hair of the Dog Dave has the highest alcohol content which is 29% ABV.
2/3 of 70% and 1/3 of 10%
Around 28% of all traffic-related fatalities in the US involve alcohol-impaired driving, according to the National Highway Traffic Safety Administration (NHTSA) data. Alcohol-related crashes remain a significant concern for road safety, and efforts to combat drinking and driving continue to be crucial in reducing these incidents.
Alcohol test ( proof ) is the percent of alcohol in drinks.
The highest level spirit it is possible to brew at all is only around 96.5%. At this point the water-alcohol solution becomes azeotropic, meaning that distillation can't separate them further.
A bottle will usually state it's alcohol by volume (ABV) as "proof" . Proof is double what the percentage of alcohol is. So, a bottle of 60 proof spirits would be 30% alcohol by volume. The highest percentage alcohol in a spirit that I've seen is 151 proof, and that was a bottle of rum.
