Question

Question 3 10 pts 0.2000kg of molten copper at the melting point 1083°C, is placed into a 375.2g aluminum calorimeter cup filled with a quantity of ice both initially at 0.000°C. If the final temperature of the system is 91.50°C, what is the mass of the ice in kilograms in the calorimeter cup initially? The specific heat for water is 4186J/kg°C, for copper is 387J/kg°C, and for aluminum is 900 J/kg°C. The latent heat of fusion for water is 3.33x109 J/kg and the latent heat of fusion for copper 1.34x109 J/kg is. Do not include units in your answer.
