Answer:
C) 170 Cal
Explanation:
We are given the composition of a food sample as;
Carbohydrate = 25 g
fat = 8 g
Protein = 5 g
We are needed to determine the energy content of the food;
We need to know the amount energy yielded by each food substance.
That is; carbohydrates and proteins generate 4 calories per gram while fats generates 9 calories per gram.
Therefore;
Amount of energy will be;
= (25 × 4 cal/g) + (8g × 9 cal/g) + (5 g × 4 cal/g)
= 172 cal
Approximately , 170 calories
Therefore, the energy content will be 170 calories
