Need help with my lab report for specific heat of unknown metal!

I need to Find the Specific Heat of Al! I know its Q= M x Cs x Change in Temp

I am getting a such a high number am just confused if its right.

Here is what I got in Lab:


Mass of Metal (Mm): 6.128g
Mass of water (Mw) : 25 mL
Temp of water in calorimeter: 23.6 C
Temp of metal in water-bath: 100 C
T Final: 28.4 C

PLS helppp.... i am stuck on this!

  • Calorimetry - ,

    The heat gained by the water in reaching equilibrium equals the heat lost by the metal. Assume that you know the specific heat of water is Cwater = 1.00 cal/g*C.
    Cmetal*6.128*(100-28.4) = Cwater*25*(28.4-23.6)
    Cmetal = 1.00*25*4.8)/[6.128*71.6]
    = 0.274 cal/(g*C)
