Question

use the following information to calculate the kilocalories found in a chocolate chip cookie that has 4.7 g of protein, 21 g of fat, and 63 g of carbohydrates.
nutrient | calories/g
fat | 9
carbohydate | 4
protein | 4
options:
88.7 kcal
460 kcal
0.0887 kcal
0.460 kcal

Explanation:

Step1: Calculate kcal from fat

Fat: \(21\space g\times9\space kcal/g = 189\space kcal\)

Step2: Calculate kcal from carbohydrate

Carbohydrate: \(63\space g\times4\space kcal/g = 252\space kcal\)

Step3: Calculate kcal from protein

Protein: \(4.7\space g\times4\space kcal/g = 18.8\space kcal\)

Step4: Sum up all kcal

Total kcal: \(189 + 252+ 18.8 = 459.8\approx460\space kcal\)

Answer:

460 kcal
