If ethanol has a density of 0.789g/ml, what would the volume of the ethanol be in ml? What would the volume be in gallons (1gal = 3785ml)?
The above ethanol could be converted to Vodka by diluting to 50% ethanol (adding enough water to double the volume). What would the volume of the resulting Vodka be in ml? If the volume of a “shot” of Vodka is 30ml, how many shots of vodka could be produced from a bushel of corn?
