At constant volume, the heat of combustion of a particular compound is -3698.0 KJ/mol. When 1.895 g of this compound (molar mass=181.06 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 8.009C. What is the heat capacity (calorimeter constant) of the calorimeter?
Assume that the metal rack is cooled from 240°F to 85°F, the temperature of the outlet water. The amount of heat removed from the retort walls in cooling from 240 to 100°F is 10 000 btu. Radiation loss from the retort during cooling is estimated a..
