Question

How many calories per gram does alcohol have?

a. 4 calories per gram
b. 7 calories per gram
c. 9 calories per gram
d. Not enough information to answer question

Answer 1

Alcohol contains 7 calories per gram, and this is measured using bomb calorimetry, a method that accurately determines the caloric content of food and beverages.

Step-by-step explanation:

The amount of calories per gram that alcohol has is 7 calories per gram. This value is quite high when you compare it to other macronutrients, such as proteins and carbohydrates, which contain 4 calories per gram. However, it is less than the amount found in fats, which contain 9 calories per gram. The caloric content of food, including alcoholic beverages, can be accurately measured using bomb calorimetry. This process involves burning the substance inside a bomb calorimeter and measuring the energy released to determine the energy content per gram.
