Kohlenhydrate

A friend returned from a week visiting family in Germany with these delicious treats as a souvenir for my daughter.

If each piece weighs 16.76 grams and a serving is 100 grams and each 100 grams has 53 grams of kohlenhydrate, then how many grams of kohlenhydrate does one piece have?

These treats appeared in time for lunch at the nurse-free summer music program my daughter attends.  She valiantly tried to figure out how many carbs each one contained but kept coming up with unreasonable sounding answers.  "So I ate one and guessed."

Who could blame her?  It's hard enough sometimes to sort out carbs on an American and english-language nutrition label.  Figuring this one out could significantly cut into a person's chocolate enjoyment.
