Beer is typically 6% ethanol. The density of ethanol is 0.789 g/mL, and a US pint is 473.18 mL. In one pint of beer, what is the mass of ethanol? Assume the alcohol percentage is (volume of alcohol) per (volume of solution).
100ml of beer has 6ml ethanol .
US pint (473.18ml) of beer has (6ml/100ml)×473.18ml = 28.3908 ml ethanol
Mass of the ethanol = 28.3908ml × 0.789g/ml
= 22.4 g (Answer)
