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 candy bar has a total mass of 75.0 grams. In a calorimetry experiment, a 1.25-g sample of this candy bar was burned in a calorimeter surrounded by 1000 g of water. The temperature of the water in contact with the burning candy bar was measured and found to increase from an initial temperature of 21.2°C to a final temperature of 24.3°C. a. Calculate the amount of heat in calories released when the 1.25-g sample burned. (show the work you did)
Consider an unknown metal X with a mass of 67.5 g at an initial temperature of 76.1 °C. The metal is placed in 88.7 g of water initially at 20.5 °C in an insulated container.

A particular container holds 3.77 mol of neon gas. The volume of this container can be altered by sliding a piston in or out. The volume is changed from 8.60 L to 12.20 L while at the same time the temperature is changed from 303 K to 345 K. The molar heat capacity, Cym, for neon is 12.47 J/(mol · K). Assume that this value will not change over the given temperature range. What is the change in entropy for the gas? AS = J/K TOOLS x10 MacBook Pro

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? Assume the temperature of the calorimeter is the same temperature as the cold water. 4.184 J/°C 132.5 J/°C
