Question
You take 326 g of a solid (melting point = 57.6oC, enthalpy of fusion = 346 J/g) and let it melt in 757
g of water, and the water temperature decreases from its initial temperature to 57.6oC. Calculate the
initial temperature of the water. (Note that the speciļ¬c heat capacity of water is 4.18 J/(goC).)

[mass solid x heat fusion] + [mass water x specific heat water x (Tf-Ti)] = 0
Substitute and solve for Ti.
Substitute and solve for Ti.
