Calculate the heat (in kJ) required to transform 43.80 g of ethanol from a solid at a temperature of -114C to a gas at 108
Calculate the heat (in kJ) required to transform 43.80 g of ethanol from a solid at a temperature of -114C to a gas at 108 C. Report your answer to one decimal place. Data:
Molar mass of ethanol = 46.069 g/mol
Melting point = -114 C
Boiling point = 79C.
Enthalpy of fusion = 4 .973 kJ/mol
Enthalpy of vaporization = 38.56 kJ/mol.
Heat capacity of the liquid phase = 112.4 J/mol K
Heat capacity of the gas phase= 65.4 J/mol K.
