<u>Answer:</u> The calorie content of the serving of cereal is 134.29 Calories.
<u>Explanation:</u>
We are given:
Average number of calories for fat = 9.1 Cal/g
Average number of calories for carbohydrates = 4.1 Cal/g
Average number of calories for proteins = 4.1 Cal/g
Mass of fat = 4.8 g
Mass of carbohydrates = 13.8 g
Mass of protein = 8.3 g
To calculate the calorie content in all the minerals, we apply unitary method:
- <u>For fat:</u>
If 1 gram of fat has 9.1 calories.
So, 4.8 grams of fat will have =
The calorie content in given amount of fat is 43.68 Calories.
- <u>For carbohydrate:</u>
If 1 gram of carbohydrate has 4.1 calories.
So, 13.8 grams of carbohydrate will have =
The calorie content in given amount of carbohydrate is 56.58 Calories.
- <u>For protein:</u>
If 1 gram of protein has 4.1 calories.
So, 8.3 grams of protein will have =
The calorie content in given amount of protein is 34.03 Calories.
Total amount of calorie in cereal = 43.68 + 56.58 + 34.03 = 134.29 Calories
Hence, the calorie content of the serving of cereal is 134.29 Calories.
