If the caffeine concentration in a particular brand of soda is 2.97 mg/oz, 2.97 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.

Explanation:

The given data is as follows.

     Concentration of caffeine = 2.97 mg/oz

     Number of oz in a can = 12 oz

Therefore, the concentration of caffeine in one can is calculated as follows.

                 = mg

                 = 35.64 mg

                 =

Since, it is given that lethal dose is 10.0 g. Hence, number of cans are calculated as follows.

     No. of cans =

                         =

                         = 280.58

                         = 281 (approx)

Thus, we can conclude that 281 cans of soda would be lethal.

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.
