Homework Help: Latent heat and specific heat in insulated container

  1. Feb 10, 2017 #1
    1. The problem statement, all variables and given/known data
    A 1.0kg of ice at 0◦C, 3.0kg of water at 0◦C, and 5.0kg of iron at temperature T are placed in a sealed and insulated container. cFe =400J/ kg◦C ,cWater=4200J/ kg◦C , cIce= 2000 J/ kg◦C

    latent heat for ice is 3.3×105 J .
    The equilibrium temperature is 20◦C.

    2. Relevant equations

    3. The attempt at a solution

    BUT the answer says it should be 353°
