Final answer:
A bag of chips labeled as containing 249 Calories has 1,041,816 joules of energy. This is based on the conversion factor that one dietary Calorie is equal to 4,184 joules.
Step-by-step explanation:
The question concerns the conversion of nutritional Calories to joules, a concept that falls under Chemistry in Everyday Life. In the context of food energy, we use the term Calories with a capital 'C', which are also known as kilocalories (kcal). When converting Calories to joules, the conversion factor we use is that one Calorie equals 4,184 joules.
To find out how many joules of nutritional energy are in a bag of chips that contains 249 Calories, we do the following calculation:
- 249 Calories x 4,184 joules/Calorie = 1,041,816 joules
Therefore, a bag of chips with a nutritional energy content labeled as 249 Calories contains 1,041,816 joules of energy.
