Answer:
9 grams of Carbohydrates
Explanation:
The energies contained by each class of these compounds are as;
(i) Fats:
1 grams of Fat contains 9 Calories
(ii) Proteins:
1 grams of Proteins have 4 Calories
(iii) Carbohydrates:
1 grams of Carbohydrates contains 4 Calories
(iv) Vitamins and Minerals:
Vitamins and Minerals have no Calories
Solution:
As 1 gram of Protein Contains 4 Calories so, we will subtract 4 Calories from the total Calories contained by the Juice as,
Calories by Carbohydrates = Total Calories - Calories by Protein
Calories by Carbohydrates = 40 - 4
Calories by Carbohydrates = 36 Calories.
Hence,
As,
4 Calories were contained by = 1 gram of Carbohydrate
So,
36 Calories will be contained by = X grams of Carbohydrates
Solving for X,
X = 36 Calories × 1 gram / 4 Calories
X = 9 grams of Carbohydrates
