Answer:
The correct answer will be-0.145 kcal/serve.
Step-by-step explanation:
The Carbohydrates on oxidation produces 4 calories per gram, the proteins provide 4 calories per gram and the Fats provides 9 calories per gram.
If one serve of crackers contains
1. Carbohydrates- 22 g, will produce calories- 22 x 4= 88 calories
2. Proteins- 3 g will produce calories- 3x4= 12 Calories
3. Fats- 5 g will produce calories- 5 x 9= 45 calorie
Therefore, the total calories in a single serve will be 88 +12 + 45
Total calorie = 145 calorie
OR
Kilocalorie= 145/1000 = 0.145 kcal/serve.
Thus, 0.145 kcal/serve is the correct answer.
