2. Ethanol (C2H5OH) melts at 114C and boils at 78C. The enthalpy of fusion of ethanol is 5.02kJ/mol, and its enthalpy of vaporization is 38.56 kJ/mol. The specific heats of solid and liquid ethanol are 0.97 and 2.3 J/gC, respectively. How much heat is required to convert 42.0g of ethanol at 35C to the vapor phase at 78C ? Answer: q=mcT=(42.0g)(2.3J/gC)(78C35C)=4153.8J
