Homework Help: Chemistry

Posted by Amalia on Wednesday, May 25, 2011 at 6:07pm.

Mercury, with a freezing point of -38.8C, is the only metal that is liquid at room temperature. How much heat energy (in joules) must be released by mercury if 1.30 mL of the metal is cooled from room temperature (18.0C) to -38.8C and then frozen to a solid? (The density of mercury is 13.6 g/cm3. Its specific heat is 0.140 J/g K and its heat of fusion is 11.4 J/g.)

Is this the type of question where you have to draw a heating curve and get your information after you draw the heating curve? What do I have to do after that?
