A jar of tea is placed in sunlight until it reaches an equilibrium temperature of 30.8°C.
In an attempt to cool the liquid, which has a mass of 175 g, 118 g of ice at 0.0°C is added.
At the time at which the temperature of the tea is 25.9°C, find the mass of the remaining ice in the jar. The specific heat of water is 4186 J/kg ° C. Assume the specific heat capacity of the tea to be that of pure liquid water.
Answer in units of g
