Are these values for percent of sugar in soda likely?

Question

Regular Dr. Pepper: 10.7%

Regular Mountain Dew: 13.6%

Original Red BullL 16.1%

Do they seem like they're too high or too low or anything? I did a lab over this and I don't know if my results seem correct?

Answer 1

I would not doubt if that's true, if not a little low. Sodas have like 45 grams of sugar per can; it's insane.
