Question

If the caffeine concentration in a particular brand of soda is 2.37 mg/oz, drinking how many cans of soda would be lethal?

Answer 1

14

Step-by-step explanation:

One can of soda contains 12 oz (355ml). Your ratio says that the brand of soda contains 2.37 mg/oz (milligrams per oz).

So, we multiply 12 (oz) X 2.37 (mg/oz), to know the exact amount of caffeine contained in one can, wich results in 28.44 mg of caffeine per can.

Now, according to the U.S. Food and Drug Administration (FDA), the lethal amount of caffein for an adult is 400 mg per day, so, in order to know how many cans would be lethal, we need to divide:

400 (mg) / 28.44 (mg), wich results in 14.06.

Finally, according to our calculations, if you drink 14 sodas that contain 2.37 mg/oz caffeine, you would die.
