A taco from a fast food restaurant contains 7.0 g of fat, 25. g of carbohydrate, and 11 g of protein. How many kJ of energy does the cheeseburger contain? (The caloric values for foods are 38 kJ/g for fat, for carbohydrate, and 17 kJ/g for protein.)

878 kJ of energy is there in cheeseburger

Explanation:

Given : calorific value of fat = 38kJ/g

calorific value of carbohydrate = 17 kJ/g

calorific value of protein = 17kJ/g

1 g of fat contains energy = 38 kJ

7.0 g of fat contains energy =

1 g of carbohydrate contains energy = 17 kJ

25 g of fat contains energy =

1 g of protein contains energy = 17 kJ

11 g of protein contains energy =

Total energy = (266+425+187) kJ = 878 kJ
