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**.
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**.
