Ethanol (C2H5OH)(C2H5OH) meltsat −−114 ∘C∘C and boils at 78 ∘C∘C. Theenthalpy of fusion of ethanol is 5.02 kJ/molkJ/mol, and itsenthalpy of vaporization is 38.56 kJ/molkJ/mol. The specificheat of solid and liquid ethanol are 0.97and 2.3 J/(g⋅K)J/(g⋅K), respectively.
A.How much heat is required to convert 22.5 gg ofethanol at 27 ∘C∘C to the vapor phase at 78 ∘C∘C?
Express your answer in kilojoules to three significantfigures.
