calculate the change in entropy that occurs when 18.53 g of ice at -10.7°C is placed in 54.05 g of water at 100.0°C in a perfectly insulated vessel. Assume that the molar heat capacities for H2O(s) and H2O(l) are 37.5 J K-1 mol-1 and 75.3 J K-1 mol-1, respectively, and the molar enthalpy of fusion for ice is 6.01 kJ/mol.
