A 16.19 g sample of metal heated in a test tube submerged in 100.00 °C water. It was then placed directly into a coffee cup calorimeter holding 51.83 g of water at 22.09 °C. The temperature of the water increased to 24.51 °C, determine the specific heat capacity of the metal. 0.4294 If the calorimeter had absorbed 197.8 J and we factored that quantity into our calculations, what would the specific heat of the metal been? 1.69 9°C

PART A: A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in calorimeter is determined to be 19.6 °C. To this is added 50.0 mL of water that was originally a temperature of 54.5 °C. A careful plot of the recorded temperature established T0 as 31.1 °C. What is the calorimeter constant (J/°C)? DensityH2O = 1.00 g/mL Specific HeatH2O = 4.184 J/g·°C PART...
