Calculate the total resistance of an electrochemical cell consisting of two half-cells where one half-cell has a copper electrode submerged in a 0.5 M CuSO4 solution, and the other half-cell has a zinc electrode submerged in a 1.0 M ZnSO4 solution. The copper electrode is connected to the zinc electrode through a salt bridge. The resistance of the salt bridge is 22 ohms, and the resistance of the copper and zinc electrodes are negligible.

Calculate the standard enthalpy change for the fusion of 100 grams of ice at 0°C to liquid water at 0°C. The specific heat capacity of water is 4.184 J/g°C, the standard enthalpy of fusion of water is 6.01 kJ/mol, and the molar mass of water is 18.015 g/mol. Assume all heat absorbed is used to melt the ice and the temperature remains constant.
