Homework Help: Molar Heat of Fusion experiment question?

  1. Jan 29, 2010 #1
    Molar Heat of Fusion experiment question!?!

    1. The problem statement, all variables and given/known data

    In one experiment heat was added to one mole of an unknown solid, at its normal melting point, at a constant rate of 13.1 J/s. If it took 2.33 minutes to melt all of the solid, what was the molor heat of fusion (in kJ/mol) of the unknown? Was the unknown water? Explain.

    2. The attempt at a solution

    13.1 J/s x (2.33 min x 60 sec) = 1831.38 J

    That's amount of heat, what is molar heat of fusion?

    What is molar heat of fusion for water?

    Are these identical?
