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 : The number of cans of soda lethal would be, 343  cans

Explanation :

First we have to calculate the amount of dose in 10 g of caffeine.

As, 2.43 mg of caffeine present in 1 oz

So, 10000 mg (10 g = 10000 mg) of caffeine present in

Now we have to calculate the number of cans used.

As, 12 oz dose present in 1 can

So, 4115.2 oz dose present in cans

Therefore, the number of cans of soda lethal would be, 343 cans
