if the caffeine concentration in a particular brand of soda is 3.67 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. cans of soda:
Answer
Explanation:
Step1: Convert lethal dose to mg
Since $1\ g = 1000\ mg$, for a lethal dose of $10.0\ g$ of caffeine, we convert it to milligrams. $10.0\ g\times1000\frac{mg}{g}=10000\ mg$
Step2: Calculate caffeine in one can
The caffeine concentration is $3.67\ mg/oz$ and a can has $12\ oz$. So the amount of caffeine in one can is the product of the concentration and the volume of a can. $3.67\frac{mg}{oz}\times12\ oz = 44.04\ mg$
Step3: Calculate number of cans
To find the number of cans needed to reach the lethal dose, we divide the lethal - dose in mg by the amount of caffeine in one can. $\frac{10000\ mg}{44.04\ mg}\approx227.066$
Answer:
227
