1. Calculate the heat lost by the hot water. (See the equation in the Introduction.) Express your answer in calories and Joules. Show your work.

    • Heat(cal)=(mass(g))(Cp)(?T)
    • Heat=(150g)( 1cal/goc)(11oC)
    • Heat=1650cal
    • 1cal=4.184J
    • 1650cal=394J

    2. Using the volume of ice melted, convert to mass of ice melted using the density of water of 1 g/mL.

    • M=DV
    • M=(1g/ml)(15.5ml)
    • M=15.5g

    3. Convert mass of ice melted to moles of ice melted.

    • Moles=g(1mol/molar mass)
    • Moles=15.5g(1mol/18.0g)
    • =.861mol

    4. Calculate the molar heat of fusion of ice in kJ/mol.
