    Find the Mass of Water that Freezes: Entropy Change Calculations

    1. At 10°C, 32 g of water is mixed with 430 g of ice at -5°C. (The heat capacity of water is 4190 J/(kg * °C), that of ice is 2090 J/ (kg *°C), and the heat of fusion of water is 3.34 * 10^5 J/kg) a) What mass of water freezes ? b) What is the change in entropy of the system? What I did on...
