The LD50 for caffeine is 192 mg/kg. How many cups of coffee would provide a lethal dose for a 150 lbs person?
( 1 cup contains 92 mg of caffeine and 2.21 lbs =1 kg)
Homework Answers
The lethal dose for caffeine (LD50) is given as 192mg/kg.
weight of person = 150lb or 68kgs
so the LD50 for person weighing 68kg = 192 mg/kgx 68Kg =13056mg
If 1 cup of coffee contain 92 mg caffeine, then 13056 mg of
caffeine will be contained in 13056mg/92mg = 142 cups.
so 142 cups of coffee would provide a lethal dose for a 150 lbs
person

For determining the toxicity of different compounds, the concept of LD50, the lethal dose for 50% of test subjects is used. The LD50 in rats for caffeine is 192mg per 1 kg of body weight. Assuming the same LD50 for humans.For a 180-lb person, calculate the number of cups of coffee that must be ingested to provide the LD50 for caffeine if one cup is 12 fluid ounces and there is 100mg of caffeine per 6 fluid ounces of drip...

A caffeine patch has been designed which releases 300 mg of caffeine over six hours. You are concerned that this patch could pose serious health risks if accidentally left on as there is no way to control the caffeine release. The patch is applied to the shoulder where the skin is 1.5 mm thick. You also know that mass diffusivity from the caffeine through the skin is 6.8 x 10-8 cm/s. The patch itself is a 4 cm x 4...
