A calorimeter is to be calibrated: 72.55 mL of water at 71.6 °C is added to a calorimeter containing 58.85 mL of water at 22.4 °C. After stirring and waiting for the system to equilibrate, the final temperature reached 47.3 °C. Determine the calorimeter constant, given that the specific heat capacity of water is 4.18 J/g°C.

A 2.49 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter with a heat capacity of 4.25 kJ/°C. If the temperature rose from 29.5 °C to 69.8 °C, determine the value of ΔH°comb for aniline.

A 21.8 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter, causing the temperature to rise from 25.0°C to 62.3°C. Given that the molar mass of ethanol is 46.07 g/mol, what is the heat capacity of the calorimeter?

A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter with a heat capacity of 14.25 kJ/°C. If the initial temperature was 32.9°C and the combustion of aniline releases 30.0 kJ/g, what is the final temperature of the calorimeter?

A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter. If the temperature rose by 32.9°C, use the information below to determine the heat capacity of the calorimeter. The balanced reaction is: 4 C6H5NH2(l) + 35 O2(g) → 24 CO2(g) + 14 H2O(g) + 4 N2(g). Given that the standard enthalpy of combustion for aniline is -3170 kJ/mol, what is the heat capacity of the calorimeter?

In a constant-volume calorimetry experiment using a bomb calorimeter, what thermodynamic quantity is directly measured?

Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 0.820 g of naphthalene burns in a bomb calorimeter, the temperature rises from 25.10 °C to 31.56 °C.
