5 . An aluminum calorimeter contains 175g of water at an initial temperature of 20c. When 50g of metal shot, at an initial temperature of 100 C, are poured quickly into the calorimeter, the calorimeter temperature rises to 30 C. Assuming no heat loss, what is the specific heat of the metal? (You may assume that the aluminum calorimeter cup has a mass of 25g, a specific heat of 0.22cal/goC, and remains in thermal equilibrium with the water)
