A well-insulated ice-water bath at 0.0°C contains 20.0 g ice. Throughout this experiment, the bath is maintained at a constant pressure of 1.00 atm. When a piece of nickel at 100.0°C is dropped into the bath, 10.0 g of the ice melts. Calculate the total entropy change for the contents of the bath (ice, water, and nickel). NOTE: enthalpy of fusion of ice = 334. J g-1. Specific heats at constant pressure: nickel, 0.46 J K-1 g-1; water, 4.18 J K-1 g-1; ice 2.09 J K-1 g-1 .
