Question

If the caffeine concentration in a particular brand of soda is 1.95 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

Number of oz in a can$=12$

Amount of caffeine in one can$=12 \times 1.95 =23.4 mg=0.0234 gm$

10 gram is a lethal dose.

So number of can a person can consume$=\frac{10}{0.0234} \approx427$
