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

    Suppose 7.67 kg of molten (liquid) lead at its melting point is poured into 764 g of water at 53.3o C. How much of the water boils?

    2. Relevant equations
    mc(detla T) = m(water)c(detla T).

    3. The attempt at a solution
    i m guessing i have to do the dollowing:
    mc(detla T) = m(water)c(detla T)+m(vapor)Lv
    am i on the right track..
    thanks in advance
