Answer 2

Answer:

841.386 kilojoules

Explanation:

A Kilojoule is a unit used to determine or measure the amount of energy that is obtained from food substances.

It is important to note that 1 Calorie is equal to 4.186 kilojoules.

From the above question, a 20 fluid oz soda contains 201 calories

Hence, the number of kilojoules it contains is calculated as:

1 calorie = 4.186kilojoules

201 calories = X

Let X be the number of kilojoules contain in a 20 fluid oz. soda

We cross multiply

X = 4.186 × 201 calories

X = 841.386 kilojoules

Hence, a 20 fluid oz. soda contains 841.386 kilojoules of energy.
