    Calculate the heat (in KJ) required to transform 43.90 g of hydrazine from a solid at a temperature of 1.4 degreed C to a gas at 128 degrees C. report your answer to one decimal place.

    Data:
    molar mass of hydrazine: 32.045 g/mol
    melting point = 1.4 degrees C
    Boiling point = 114 degrees C
    Enthalpy of fusion = 12.6 KJ/mol
    Enthalpy of vaporization = 41.8 KJ/mol
    Molar heat capacity of the liquid phase = 98.9 J/mol x K
    Molar heat capacity of the gas phase = 49.6 J/mol x K
