Question

An 8 oz. bottle of energy drink contains 6.0 g of protein, 2.0 g of fat, and 16.3 g of carbohydrate. The fuel value of this energy drink bottle is ________ kJ. The fuel values for protein, fat, and carbohydrate are 17, 38, and 17 kJ/g, respectively.

a. 280
b. 720
c. 72
d. 460
e. 520

Answer 1

Answer: The correct option is d) 460 kJ

Step-by-step explanation:

We are given:

Content of fat in energy drink = 2.0 g

Content of protein in energy drink = 6.0 g

Content of carbohydrate in energy drink = 16.3 g

Also,

The fuel value of fat = 38 kJ/g

The fuel value of protein = 17 kJ/g

The fuel value of carbohydrate = 17 kJ/g

So, the fuel value of the energy drink will be:

Total fuel value =
`(2.0g* 38 kJ/g)+(6.0g* 17 kJ/g)+(16.3g* 17 kJ/g)`

Total fuel value =
`[76+102+277]=460kJ`

Hence, the correct option is d) 460 kJ
