Question

A food product contains 15 g of carbohydrates (CHO), 5 g of protein (PRO), and 4 g of fat. How many calories are in one serving of this product?

Answer 1

There are 116 calories in one serving of this product.

Step-by-step explanation:

Step 1: Data given

Mass of carbohydrates = 15.00 grams

Mass of proteins = 5.00 grams

Mass of fat = 4.00 grams

1 gram carbohydrates provides 4 calories (per gram)

1 gram proteins provides 4 calories (per gram)

1 gram fat provides 9 calories (per gram)

Step 2: Calculate total calories for this product

Total calories = 4 calories/ gram * 15.00 grams + 4 calories/gram * 5.00 grams + 9 calories / gram * 4.00 grams

Total calories = 60 + 20 + 36 = 116 calories

There are 116 calories in one serving of this product.

Answer 2

116 Cal

Step-by-step explanation:

15 g CHO × 4 Cal/g = 60 Cal

5 g PRO × 4 Cal/g = 20

4 g fat × 9 Cal/g = 36

TOTAL = 116 Cal

There are 116 Cal in one serving of the product.
