( m Cp dT ) hot water = (m Cp dT )cold water + (Cp dT)cold
50 x 4.184 x (32.17-24.55) = (50 x4.184 x (24.55 - 19.09) ) + Cp ((24.55 - 19.09))
1594 = 1142 + 5.46 Cp
Cp = 82.8 J / oC
calorimeter constant = 82.8 J / oC

1.A student determined the calorimeter constant of the calorimeter, using the procedure described in this module. The student added 50.00 mL of cold water to 50.00 mL of heated, distilled water in a Styrofoam cup. The initial temperature of the cold water was 19.09°C and of the hot water, 32.17°C. The maximum temperature of the mixture was found to be 24.55°C. Assume the density of water is 1

A student heats 84.17 mL of water to 95.27°C using a hot plate. The heated water is added to a calorimeter containing 73.92 mL of cold water. The water temperature in the calorimeter rises from J 2.15°C to 40.70°C. The specific heat capacity of water is 4.184 and the density of water is g. °C 1.00 mL Assuming that heat was transferred from the hot water to the cold water and the calorimeter, determine the heat capacity of the calorimeter....
