In order to answer this question, you need the specific heat of fusion (freezing) of benzene. Perhaps there is a table in your book of those values? –  Ben Norris Dec 10 '12 at 11:17

This question is asking you to use a little bit of critical thinking, or, applying multiple concepts of what you have learned. I will help you get started and the goal is that you will be that much better at solving problems on your own.

It follows that you should ask yourself this question:

What information do you think will be useful to answer this question?

I will help you:

What else do I need to know about benzene to answer this problem? (is there missing information?)

Why did they give me grams of benzene in the question? (is that even necessary?)

What is the difference between heat and temperature? (important, think about it)

Please comment if you still are having trouble, or edit your question to reflect your progress since you might not be able to comment.

Here is the answer when you are ready.

Heat of fusion is necessary and missing. Grams are put in there because the more you have to melt the more heat you have to put in to get the same results(such as melting something). This is how come a few ice cubes melts much faster than a glass full of ice. Heat is the energy put in or released to increase the temperature or change it to another state of matter in which case the temperature stays constant for that period of time –  caters Oct 6 at 12:32
