Homework Help: Chemistry

Posted by James on Friday, February 17, 2012 at 1:58pm.

I am lost about where to start on this.
"The idea comes to mind to put some hot rocks in your frozen bath water. What mass of rocks at 220 degrees Celsius needs to be added to 500.0L of frozen bath water at 0 degrees celsius to raise its temperature to 55 degrees celsius? The specific heat of the rcks is 2.5cal/g-C* and that of water is 1cal/g-C*. The heat of fusion for ice is 80cal/g. Assume there is no heat transfer between the ice/water and the walls of your bath.

Any help is GREATLY appreciated
