Question

If a potato contains 23.0g of carbohydrates with a caloric value of 4.0 kcal/g, how many kcal are obtained from the carbohydrate?

a) 46 kcal
b) 92 kcal
c) 9.2 kcal
d) 92.0 kcal

Answer 1

The caloric content obtained from 23.0g of carbohydrates in a potato, with a caloric value of 4.0 kcal/g, is 92 kcal. The correct answer is (b) 92 kcal.

Step-by-step explanation:

To calculate the caloric content from the carbohydrates in a potato, we use the equation:

Calories = mass of carbohydrate × caloric value per gram

In this case, the mass of carbohydrate in the potato is 23.0 grams and the caloric value is 4.0 kcal/gram. Therefore, the total caloric content obtained from the carbohydrate is:

Calories = 23.0g × 4.0 kcal/g = 92 kcal

So, the correct answer is (b) 92 kcal.
