On a 10.5 ounce bag of potato chips, the manufacturer states that the single serving is one ounce, which is equivalent to 150 calories. How many kilojoules are in this bag of potato chips?
Is it 6.5898kJ?
Isn't it 150 kcal (a nutritional calorie in actuality is a kcal) x 4.184 J/cal = 627.6 kJ.
To calculate the number of kilojoules (kJ) in a bag of potato chips, we need to convert the calories to kilojoules.
The conversion factor is as follows: 1 calorie is equal to approximately 4.184 kilojoules.
Given that a single serving of potato chips is 150 calories, we can calculate the number of kilojoules by multiplying the number of calories by the conversion factor:
150 calories * 4.184 kilojoules/calorie = 627.6 kilojoules
Therefore, the correct answer is 627.6 kJ, not 6.5898 kJ.
