Question: Calculate the change in entropy that occurs when 18 02 g
Calculate the change in entropy that occurs when 18.02 g of ice at 210.0oC is placed in 54.05 g of water at 100.0oC in a perfectly insulated vessel. Assume that the molar heat capacities for H2O(s) and H2O(l) are 37.5 JK-1mol-1 and 75.3 JK-1mol-1, respectively, and the molar enthalpy of fusion for ice is 6.01 kJ/ mol.
