Chapter 5: Q37E (page 270)

A serving of a breakfast cereal contains 3g of proteins, 18g of carbohydrates, and 6g of fat. What is the calorie content of a serving if the average number of calories for fat is 9.1 Calories/g, for carbohydrates is 4.1Calories/g, and for protein is 4.1Calories/g?

Short Answer

Expert verified

The total calorie content of a serving is 140.7 cal.

Step by step solution

01

6 g of fat

It is given that the calorie content for fat is 9.1 cal/g

So, for 6 g of fat, the total calories = 6 g 脳 9.1 cal/g = 54.6 cal

02

18 g of carbohydrate

It is given that the calorie content for carbohydrates is 4.1 cal/g

So, for 18 g of carbohydrate, the total calories = 18 g 脳 4.1 cal/g = 73.8 cal

03

3 g of protein

It is given that the calorie content for protein is 4.1 cal/g

So, for 3 g of protein, total calories = 3 g 脳 4.1 cal/g = 12.3 cal

04

Total calorie

So, finally, the calorie content of the serving will be

= 54.6 cal + 73.8 cal + 12.3 cal

= 140.7 cal
