Answer 1

To convert from nutritional calories (Cal) to kilojoules (kJ), we use the conversion factor:

1 nutritional Cal = 4.184 kJ.

Now we can convert \(5.89 \times 10^{-1}\) nutritional calories to kilojoules:

\[ 5.89 \times 10^{-1} \text{ Cal} \times 4.184 \text{ kJ/Cal} = 2.464056 \text{ kJ} \]

Now, rounding to three significant figures gives:

\[ 2.46 \text{ kJ} \]

Thus, \(5.89 \times 10^{-1}\) nutritional Cal is approximately 2.46 kJ.
