12 oz = 354.88ml of beer (this is generally considered a serving.)
now, if the beer is 4.5% by volume alcohol
354.88ml * .045 = 15.9696ml alcohol.
Assuming that 1 ml of alcohol is 1g (which is fairly accurate) then there are about 16g alcohol in a beer.
If the beer is stronger, say 6%:
354.88ml * .06 = 21.2928g alcohol...
Yes, every alcoholic drink has, specifically, ethanol.
Ethanol is a pure substance, but it is rare to encounter it pure. Laboratory alcohol usually contains small amounts of water and methanol. Alcoholic drinks contain large quantities of water, as well as flavourings.
A typical drink contains less than 40% alcohol. Beer is normally under 6%, wine under 15%, and most spirits are no more than 40% Ethanol is pure alcohol, IE 100%. Hence if one drinks one pint of ethanol it is equivalent to roughly 20 pints of beer. 20 pints of beer takes a long time to consume, and also contains 19 pints of water. The pint of ethanol enters your system in a fraction of the time the same amount of ethanol would do if mixed with beer. It also lacks the 19 pints of water that would be consumed along with the ethanol. The 19 pints of water would be used to "flush" out some/much of the ethanol as the drinker would no doubt urinate many times during the time taken to consuming 20 pints of beer. Also consider that the drinker of beer can "stop" part way through, while the drinker of a pint of ethanol can't, as it has all been consumed before it takes effect.
Yes, as long as a substance is 100% (purity), it is considered as a pure substance. But logically, there is no such thing as a pure substance.
There is only one type of drinkable alcohol - ethanol. To get drunk it depends on the person. .08 in most states (if not all) is legally drunk. That is an average four drinks at one ounce of pure ethanol per drink. One drink can be: a beer, 8oz of wine, 1 shot of hard proof liquor, or one mixed drink.
12 ounces of beer delivers approximately half an ounce of ethanol.
Ethanol is an alcohol with 2 carbon atoms and one OH group. It is often called drinking alcohol and is present in beer, wine and hard liquorl. It can be produced by the fermentation of staches or sugars.
Chemically speaking alcohol is meant to be ethanol, which is a pure compound with formula CH3CH2OH, it definitely is not a mixture, except when 'dissolved' in water (most stable solution: 4% water + 96% ethanol. (This is what you get when buying a bottle pure ethanol)rubbing alcohol is a mixtureIf you were to take 'alcohol' into a more specific definition an alcohol is really a hydrocarbon with the functional groupSo if it were, well i would say, 100% ethanol then it would be a compound.
One could perform a simple density measurement to distinguish between ethanol and a mixture of ethanol and sucrose. Since sucrose has a higher density than ethanol, the density of the mixture would be higher than that of pure ethanol. Additionally, one could analyze the liquid using a technique such as gas chromatography to separate and identify the individual components present in the liquid.
A single shot of any liquor that is at least 40% ABV will contain the same amount of ethanol as in one serving (a pint or bottle) of 5% ABV beer or more.
Too much ethanol causes one to make grammar mistakes, as you so kindly showed for us.
Grain alcohol is a compound known as ethanol and so is a pure substance, but it is almost never found in pure form.
