The human body is mostly made up of water (H2O), and there is one oxygen atom in each molecule of water. Note that, although each water molecule also contains two hydrogen atoms, the atomic mass of hydrogen (about 1) is much smaller than the atomic mass of oxygen (about 16). Because of this, hydrogen contributes less to human body mass than oxygen.
Answer:
The correct answer will be-0.145 kcal/serve.
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.
