Question

A potato contains 20 g of carbohydrates. If the carbohydrate has a caloric value of 4 kcal/g, How many kcal are obtained from the carbohydrate in the potato? A. 20 kcal B. 40 kcaloriesC. 60 kcalories D. 80 kcalories

Answer 1

Explanations:

The formula for calculating the amount of carbohydrate in the potato is expressed as:

`amount=mass\text{ of CHO}* caloric\text{ value}`

Given the following parameters:

Mass of CHO = 20 g

caloric value = 4kcal/g

Substitute the parameters into the formula

amount of kcal = 20g * 4kcal/g

amount of kcal obtained = 80kcal

Hence the amount of kcal obtained from the carbohydrate in the potato is 80kcal
