Which of the following energy quantities is equivalent to 578 J?

Explanation:

The answer choices are:

You must use the conversion factors to convert J to kcal.

        Dividing both sides by 4.184J:

        ⇒ 1 = 1cal/4.184J

       Dividing both sides by 1,000 cal

        ⇒ 1 = 1kcal / 1,000 cal

Mutiply 578J by the conversion factors to find kcal:

Notice how the units J and cal cancel to yield kcal at the end.
