5장, 문제 93a

(a) A serving of a particular ready-to-serve chicken noodle soup contains 2.5 g fat, 14 g carbohydrate, and 7 g protein. Estimate the number of Calories in a serving.

검증된 단계별 안내
1
Identify the caloric values for each macronutrient: fat provides 9 Calories per gram, carbohydrates provide 4 Calories per gram, and protein provides 4 Calories per gram.
Calculate the Calories from fat by multiplying the grams of fat by the caloric value per gram: \(2.5 \text{ g} \times 9 \text{ Cal/g}\).
Calculate the Calories from carbohydrates by multiplying the grams of carbohydrates by the caloric value per gram: \(14 \text{ g} \times 4 \text{ Cal/g}\).
Calculate the Calories from protein by multiplying the grams of protein by the caloric value per gram: \(7 \text{ g} \times 4 \text{ Cal/g}\).
Add the Calories from fat, carbohydrates, and protein to estimate the total number of Calories in a serving of the soup.
