The lethal dose (LD50) for caffeine is 200 mg/kg and each
cup of coffee contains 90 mg caffeine.
a) How many cups of coffee should a person of 80 kg should
drink at once to reach the lethal dose?
b) If the person were to drink one cup of coffee per day for
this number of days (calculated in 1) a)), would s/he be likely
to die from an overdose of caffeine?
c) If the person could drink exactly the number of cups of
coffee you calculated in a) all at one sitting, would the person
be guranteed to die? Why or why not?
