How do you know how much caffeine is in something?

Question

i want a 32 oz dr.pepper and a crunch bar. how much caffeine is in that?

Answer 1

In a 32 oz bottle of Dr. Pepper there are about 90 mg of caffeine. 39.6 in a 12 oz bottle, if you want to make sure and do the math.

In a Nestle Crunch Bar there are 10 mg.

So you definitely will not go over 200 mg. Enjoy.
