Energy value per gram of alcohol is

Options

A. 4 kcal
B. 4.3 kcal
C. 9.3 kcal
D. 7.1 kcal.

Answer

To determine the energy value per gram of alcohol, we can follow these steps:

1. **Understanding the Energy Content**: Alcohol, like other macronutrients, provides energy measured in calories. The energy content of alcohol is typically expressed in kilocalories.

2. **Identifying the Energy Value**: It is known that alcohol contains approximately 7 calories per gram. This is a standard value used in nutritional science.

3. **Converting to Kilocalories**: Since 1 kilocalorie (kcal) is equivalent to 1,000 calories, we can express the energy value of alcohol in kilocalories. Therefore, 7 calories per gram of alcohol is equal to 0.007 kilocalories per gram.

4. **Comparing with Options**: The options provided are 4 kilocalories, 4.3 kilocalories, 9.3 kilocalories, and 7.1 kilocalories. The closest value to the known energy content of alcohol (7 calories) is 7.1 kilocalories.

5. **Conclusion**: Based on the information and calculations, the energy value per gram of alcohol is 7.1 kilocalories.

**Final Answer**: The energy value per gram of alcohol is 7.1 kilocalories.
