Question

If a bottle of beer has 15 grams of carbohydrate, 0 grams of fat, 1 gram of protein and 15 grams of alcohol, approximately how many calories does it contain?

Answer 1

A bottle of beer with 15 grams of carbohydrate, 0 grams of fat, 1 gram of protein, and 15 grams of alcohol contains approximately 170.6 calories.

Step-by-step explanation:

The number of calories in a bottle of beer can be calculated by multiplying the grams of each macronutrient by their respective calorie values and then summing them up. In this case, there are 15 grams of carbohydrate and 1 gram of protein, which contribute 4.1 calories per gram. There are also 15 grams of alcohol, which contributes 7 calories per gram. Since the bottle has 0 grams of fat, we don't need to consider its contribution. Therefore, the total calorie content of the beer is:

(15 grams of carbohydrate × 4.1 calories/gram) + (1 gram of protein × 4.1 calories/gram) + (15 grams of alcohol × 7 calories/gram) = 61.5 + 4.1 + 105 = 170.6 calories.

Answer 2

Fat: 1 gram = 9 calories, Protein: 1 gram = 4 calories, Carbohydrates: 1 gram = 4 calories, Alcohol: 1 gram = 7 calories

From the question given above, a bottle of beer contains 15 grams of carbohydrate, 0 grams of fat, 1 gram of protein and 15 grams of alcohol.

15 g of carbohydrate = 15 x 4 = 60 calories

0 g of fat = 0 calories

1 g of protein = 1 x 4 = 4 calories

15 g of alcohol = 15 x 7 = 105 calories

60 + 0 + 4 + 105 = 169

Therefore a bottle of beer contains 169 calories.
