How many kcalories are provided by 100 grams of carbohydrate?

0.4 Kilocalories

Explanation:

Calorie is often defined as the amount of energy required to lift the temperature 1 gram of water by 1 degree celsius. The value of this Calorie can be expressed in terms of both grams as well as Kilocalories.

According to the given condition,

Firstly, the unit is to be converted from grams (g) to Calories (Cal)

1 gram of Carbohydrate provides= 4 calories

Therefore, 100 gram of Carbohydrate provides= 400 calories

Now, the unit is to be converted from Calories (Cal) to Kilocalorie (KCal)

Since, 1000 calories= 1 Kilocalories

So, 400 calories= 0.4 Kilocalories.

Hence, 100 grams of Carbohydrates provide 0.4 Kilocalories.
