Question
** 2 Parts** A blood concentration of .250% of ethanol C2H5OH can induce unconsciousness. In the US a 12 fluid ounce glass of beer containing 5.00% of ethanol is considered to be 1 standard drink.
A) How many glasses of beer would a man with a blood volume of 6.10 L have to drink in order to deliver .250% alcohol into the blood?
B) Explain why the man does not actually become unconsciius by drinking this amount of beer.
*** PLease show work so I can follow set-up to solution. Thanks!!**
Info:
Density of C2H5OH: 0.789 g/cm3
1 fl oz = 29.57 mL
1 cm3 = 1 mL
MW of C2H5OH = 46.0 g/mol
Explanation / Answer
A) 0.25% of volume of blood will be:
(0.25/100) * 6.1 L = 0.01525 L
So it needs that amount of ethanol to get unconscious
Then, to determine amount of alcohol needed, first for one beer:
12 fl oz * (29.57 mL / 1 fl oz) = 354.84 mL
354.84 mL * 0.05 = 17.742 mL = 0.017742 L
In theory, it will need:
0.01525 / 0.017742 = 0.8595 glasses
However, the drank is not taken rapidly, but gradually. So concentration will be lowered as it consumes gradually. Also, if the stomach was occupied, alcohol will delay itself to get to the bloodstream.
