If a meal supplies 110 g of carbohydrates, 25 g of protein, 20 g of fat, and the equivalent of 5 g of alcohol, what % of the kca
mars1129 [50]

Answer:

0.058 % kcalories comes from carbohydrate.

Explanation:

1 g of carbohydrtes gives 4 calories, 1 g of protein gives 4 kcalories, 1 gm of fat gives 9 calories and 1 g of alcohol gives 7 calories of energy.

Thus in a meal  that contains 110 g carbohydrates gives 110 x 4 = 440 calories,  25 g protein gives 25 x 4 = 100 calories, 20 g fat gives 20 x 9 = 180 calories and 5 g alcohol gives 5 x 7 =  35 calories.

Total calories in a meal  440+100+180+35 = 755.

Therefore % of carbogydrate will be 440x 100 divided by 755 = 58.27 %

In kcalories % would be 58.27/1000 = 0.5827 %
