A student determined the calorimeter constant of the calorimeter. The student added 50.00 mL of cold water to 50.00 mK of heated , distilled water in a styrofoam cup. The initial temp of the cold water was 21,00C and the hot water, 29.15C. The maximum temp pf the mixture was found to be 24.81C. Assume the density of water is 1.00g mL-1 and the specific heats is 4.184 J g-1 K-1

1) Determine the temp change for the hot water and cold water.

  • CHEMISTRY!! - ,

    [Mass cold water x specific herat x (Tfinal-Tinitial)] + [mass hot water x specific heat x (Tfinal-Tinitial)]
    Calculate Tfinal.
    Then subtract Tfinal-24.81 to obtain delta T.
