Question

If the caffeine concentration in a particular brand of soda is 2.13 mg/oz, drinking how many cans of soda would be lethal? Assume that 10.0 g of caffeine is a lethal dose, and there are 12 oz in a can. cans of soda:

Answer 1

400 cans of soda would be lethal.

Step-by-step explanation:

In a can of soda, there is (2.13 mg/oz * 12 oz) 25 mg caffeine.

25 mg * (1g / 1000 mg) = 0.025 g

If in a can of soda there is 0.025 g of caffeine, a lethal dose of caffeine will be ingested after drinking (10.0 g * (1 can / 0.025 g)) 400 cans of soda.
