QUESTION:
How many joules of nutritional energy are in a bag of chips with a label that lists 245 Cal? If 1 lb of fat is stored by the body for each \(14.6\times10^3\mathrm{\ kJ}\) of excess nutritional energy consumed, how many bags of chips contain enough nutritional energy to result in 1 lb of body fat?
ANSWER:
Step 1 of 2
The nutritional energy in a bag of chips is listed as 245 Cal. To convert calories into joules, we can use the conversion factor that 1 Cal is equal to 4.184 kJ:
\(245 \mathrm{Cal} \times 4.184 \mathrm{~kJ} / \mathrm{Cal}=1025.68 \mathrm{~kJ} \text {. }\)
So, a single bag of chips contains 1025.68 kJ of nutritional energy.
