One serving of peanut butter contains 5.0 g of carbohydrate, 12 g of fat, and 6.0 g of
larisa [96]

The serving of peanut butter contains 117kcal

<h3>Calculation of calories of food Nutrients</h3>

1 gram of both carbohydrate and protein contains 4 (kcal)

1 gram of fat contains 9 (kcal)

But peanut butter contains 5g of fat. The kilocalories of fat present is;

1 g = 9 kcal

5g = F

F = 5×9

F = 45 kcal

The kilocalories of carbohydrates present is;

1g = 4kcal

12g = C

C= 12×4

C = 48kcal

The kilocalories of proteins present is;

1g = 4kcal

6 g = P

P = 4× 6

P = 24 kcal

Therefore, the total kilocalories of the peanut = 45 + 48 + 24 = 117kcal
