Not only show me the answer but also show me the steps as to how you got each answer for all 5 questions. Document Preview: Heat of Fusion or Vaporization Calculations 1. How much heat is required to vaporize 343g of liquid ethanol (C2H5OH) at its boiling point? (Hvap= 38.6 kJ/ mol) ** must convert grams to moles** 2. How much heat is involved when 1,255 grams of ice melts to a liquid at 0? C? (Hfusion= 333.55 J/g) 3. How many joules are released when 50.0 grams of liquid water becomes steam? (Hvap= 40.65 kJ/ moles) 4. How many joules are absorbed when 100.1 grams of methane (CH4) melts to a liquid? (Hfusion= 8.19 J/g) 5. Calculate the heat required to melt 25.7g of solid methanol (CH3OH) at its melting point.
