Problem:
What I've done:
I know the ice has to be broken down into three equations. (q = mC(T1-T2))
I've gotten the heat, q, for the change in temperature from -9.3 -> 0 C. But, from here, I have no idea. I'm assuming I have to do something with the enthalpy fusion number in the second equation, get some answer, then use that answer in the third equation and equate it to the equation for the water.
(q I got for the first ice equation is 391.6 Joules).
So, yeah. Any suggestions as to what I should do?
