Question

If the caffeine concentration in a particular brand of soda is 2.01 mg/oz, drinking how many cans of soda would be lethal? assume 10.0 grams of caffeine is a lethal dose, and there are 12 oz in a can.

Answer 1

1 can of soda has 12 ounces * 2.01 mg/oz = 24.12 mg of caffeine.

1 gram = 1000 mg

10 grams x 1000 mg = 10,000 mg

Divide total mg by mg per can:

10,000 / 24.12 = 414.59 cans

Round to 415 cans
