Final answer:
If you drank the entire bottle, you consumed 200 kcal.
Step-by-step explanation:
To find out how many kilocalories (kcal) you consumed if you drank the entire bottle, you need to know the serving size and calories per serving. The food label states that the serving size is ½ bottle and the calories per serving are 100 kcal. Since ½ bottle is the serving size, drinking the entire bottle means you consumed 2 servings. Therefore, you consumed a total of 200 kcal (2 servings x 100 kcal per serving).
