You weighed your empty insulated cup and found that the mass of the cup was 3.1 g. You add some hot water and find that the total mass increases to 24.9 g. You got some ice from the bus tub, and found that it was wet. After drying it carefully, you take the temperature of the hot water in the cup and find that its temperature is 64.8 °C and then add the ice. The temperature of the water dropped, and came to equilibrium at 33.4 °C. At the end of the experiment you re-weigh the cup and find that the mass has increased to 30.1 g. What was the initial temperature of the ice?
