Serving Size and Quantity Calculation

Understanding serving size is crucial for determining the total quantity of items in a package. In this case, the serving size of 9 pieces corresponds to 41 grams. By calculating how many servings are in the total weight of the bag, one can then multiply the number of servings by the number of pieces per serving to find the total number of Kisses.
