Answer & Explanation:For this assignment, you are to set up the steps and show the work which should equal the answers provided. Unit 3 Lesson 5: Water Apply Vaporization. Make sure that you are showing each step of your work.1. How much energy is absorbed when 30.3 g of liquid water boils? answer= 68.5kj2. An energy unit often encountered is the calorie (4.18 J = 1 calorie). Determine the molar enthalpy of fusion of ice in calories per gram. answer = 79.8 cal/g3. A typical ice cube has a volume of about 16.0 mL. Calculate the amount of energy needed to melt the ice cube. (Density of ice at 0.°C 0.917 g/mL; molar enthalpy of fusion of ice 6.009 kJ/mol;molar mass of H2O 18.02 g/mol.)Determine the mass of the ice cube. answer = 14.7gDetermine the number of moles of H2O present in the sample. answer = 0.814 molDetermine the number of kilojoules of energy needed to melt the ice cube. answer = 4.89kjMake sure to show your work, and your answers should be provided with the correct amount of significant figures.
