What is the weight of a mouthful of fries?

The weight of a mouthful of fries can vary depending on the size of the fries and the individual's mouth capacity, but it typically ranges from about 20 to 30 grams. A standard serving of fries contains approximately 150-200 grams, so a mouthful would be a small fraction of that. Ultimately, the exact weight will depend on how many fries one can fit in their mouth at once.
