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?
