A certain alcohol has a specific heat of 0.57 cal/g\deg C and a melting point of -114\deg C. You have a 150 g cup of liquid alcohol at 22\deg C and then you drop a 10 g frozen piece of alcohol at -11\deg C into it. After some time the alcohol cube has melted and the cup has come to a common temperature of 7\deg C. What is the latent heat of fusion( i.e. the "L" in the Q = mL equation) for this alcohol?
