9. A researcher sets out to calibrate a solution calorimeter. The researcher first adds a 75.000 mL sample of water to the calorimeter, measuring a temperature of 22.4°C after the water and calorimeter reach thermal equilibrium. The re- searcher then heats a separate 75.00 mL sample of water to 40.1°C and adds this sample to the previous one in the calorimeter. After the water has mixed and a new thermal equilibrium with the calorimeter is reached, a temperature of 27.0°C is measured. What is the heat capacity of the calorimeter?

A student is attempting to determine the heat capacity of a Styrofoam cup calorimeter by pouring hot water into a Styrofoam cup containing cold water. The student determined the mass of the cold water to be 21.2455 g and its initial temperature to be 20.36 °C. The mass of the hot water was 24.2646 g and its initial temperature as 34.54 °C. The final temperature of the water after mixing was determined to be 24.57°C. The specific heat capacity of the water is 4.184 J/(g•°C). What is the heat capacity of the Styrofoam cup calorimeter?
