A cube of solid benzene (C6H6) at its melting point and weighing 8.37 g is placed in 19.3 g of water at 38.8 °C. Given that the heat of fusion of benzene is 9.92 kJ/mol, to what temperature will the water have cooled by the time all of the benzene has melted. You can assume that the benzene remains at its melting point.
