Question

If the caffeine concentration in a particular brand of soda is 1.83 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.

Answer 1

Find the caffeine mass in one can of soda

$m=1.83·12=21.96mg=0.02196g$

find the number of cans needed to get a lethal dose of caffeine.

$n=10/0.02196=455.4 cans$

Answer 455.4 cans
