Question

The grams of carbohydrate in one apple if the apple has no fat and no protein and provides 72 kcal of energy. What ate the kilocalories or kJ?

Answer 1

One calorie is equivalent to 4.184 joules. If an apple has 72 kilocalories of energy, knowing that 1 kilocalorie is equal to 1000 calories, then it has 72000 calories. Then to convert it to joules multiply it by 4.184. Then you have _ joules. Then concvert it to kilojoules by dividing it by 1000, you have 301.248.
