Legend has it that the Greek philosopher, Socrates, died after drinking a tea made from hemlock leaves. Coniine, the toxic compound found in hemlock, is calculated to have an LD50 in humans of 10 mg/kg. If we assume Socrates weighed 200 lbs, how many grams of coniine would he have needed to ingest to give a 50% chance of causing his death? If Coniine is about 3% by weight of the hemlock leaves, how many grams of hemlock would need to be used to make the tea?
