posted by on .

How much heat is evolved when 25.5 g of benzene freezes at 5.5 Celcius (molar heat of fusion is 9.94 kJ/mol and molar mass of benzene= 78.0 g/mol)

  • Chem 2 enthalpy - ,

    q = mass x delta Hfusion.
    Change 25.5 g to moles. moles = grams/molar mass.

    Note the correct spelling of celsius.
