The 1875 Chamber Street fire claimed many victims. A whiskey distillery in Dublin went into flames and released a river of whiskey, crowds gathered along the stream of alcohol to scoop up the liquor using caps, porringers, and other vessels. In all, 13 people died, not because of the fire, but ofalcohol poisoning. a. If the average human weights 137 pounds, the Human LD50 of ethanol is ~2000mg/kg. And the typical content of alcohol in whiskey is 40% . How much alcohol does the average human must drink to succumb to alcohol poison. Assume the density of whiskey is 1 so that 1 ml of whiskey is 1 gram of whiskey. In addition, assume that the LD50 is the amount required to succumb to alcohol poison.
Why do you multipy the # of H2S mols by 4, when 4 corresponds to the reactory amount of O2?The logic there is somewhat confusing to me.I understand how/why you found out the mols of the equation but dividing the sample's MM by the equation confuses me.
