Question

If the caffeine concentration in a particular brand of soda is 2.43 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

The number of cans will be, $n=\frac{lethal \space dose}{m(can)\times c(soda)}=\frac{10}{12\times 2.43\times 10^{-3}}= 343 cans$
