    1) (Hvap) (moles of water) = 236.9783574kJ

    (40.67) (105/18.02)

    2) (change in temperature) (mass) (Cliquid) = 43.9345172kJ

    (100) (105/18.02) (75.4) / 1000

    3) (Hfus) (moles of water) = 35.01942286kJ

    (6.01) (105/18.02)

    4) (change in temperature) (mass) (Csolid) = 3.181465039kJ

    (15) (105/18.02) (36.4) / 1000

    Total released=319.1137625kJ
