How many kcals will 150g serving provide?

To determine the number of kilocalories (kcals) in a 150g serving, you need to know the caloric content per gram of the specific food item. For example, if a food has 2 kcal per gram, then a 150g serving would provide 300 kcals (150g x 2 kcal/g). Please provide the specific food item for a more accurate calculation.
