Questions: A typical candy bar contains 281 food calories, which is 281 kcal . How many kilojoules are contained in one such candy bar?

Solution Steps

To convert food calories (kcal) to kilojoules (kJ), we need to use the conversion factor: \[ 1 \text{ kcal} = 4.184 \text{ kJ} \]

Given that one candy bar contains 281 kcal, we can convert this to kilojoules by multiplying by the conversion factor: \[ 281 \text{ kcal} \times 4.184 \text{ kJ/kcal} \]

\[ 281 \times 4.184 = 1176.704 \text{ kJ} \]
