Mr. Tse has a glass of water with a volume of 250 mL and a temperature of 12 degrees Celsius. He add a piece of dry ice, CO2(s), which has a mass of 25 g, to cool down his water. If dry ice has an enthalpy of sublimation of 25.2 kJ/mol, calculate the final temperature of the water after the dry ice has fully dissolved.
