KH = 6.1 x 10-4...
What about the Heat of fusion for the ice melting?
I figured it had something to do with finding the energy to melt the ice (the phase change part) plus the energy as the ice goes up to 75 degrees, and then set the combination equal to the mass of the solution x the specific heat of water x the...
