Use Hvap of water = 40.7 kJ/mol, c of water = 4.184 J/g.°C, and molar mass of HO = 18.02 g/mol. (a) Calculate the heat required to vaporize 45.0 g of water at 100 °C. (b) In a coffee-cup calorimeter, 12.0 g of ice at 0.0 °C is added to 120.0 g of water at 30.0 °C. After all the ice melts, the final temperature is 20.0 °C. Assuming no heat is exchanged with the surroundings, calculate the molar heat of fusion of ice in kJ/mol. Solve on paper and upload a clear photo or screenshot of your work.
