Final answer:
A 5 fluid oz glass of red wine with 2.4 g of carbohydrates and 14.5 g of alcohol contains approximately 111.34 calories, calculated by using 4.1 kcal/g for carbs and 7 kcal/g for alcohol.
Step-by-step explanation:
To calculate the number of calories in a 5 fluid oz glass of red wine that contains 2.4 g of carbohydrates and 14.5 g of alcohol, we can use the known caloric content of carbohydrates and alcohol per gram. One gram of carbohydrate contains approximately 4.1 kcal, and one gram of alcohol (ethanol) contains approximately 7 kcal. Applying these values:
- Carbohydrate calories = 2.4 g × 4.1 kcal/g
- Alcohol calories = 14.5 g × 7 kcal/g
By adding the two results together, we can determine the total caloric content of the wine.
Calculation Steps:
- Multiply 2.4 g of carbohydrates by 4.1 kcal/g to get the calories from carbohydrates.
- Multiply 14.5 g of alcohol by 7 kcal/g to get the calories from alcohol.
- Add the calories from carbohydrates and alcohol to get the total calories in the wine.
So, the calculations would be:
Carbohydrate calories = 2.4 g × 4.1 kcal/g = 9.84 kcal
Alcohol calories = 14.5 g × 7 kcal/g = 101.5 kcal
Total calories = 9.84 kcal + 101.5 kcal = 111.34 kcal
Therefore, a 5 fluid oz glass of red wine would contain approximately 111.34 calories.
