A 2.017g sample of a new organic material is combusted in a bomb calorimeter. The temperature of the calorimeter and its contents increase from
25.09∘C to 32.06∘C.
The heat capacity (calorimeter constant) of the calorimeter is 43.29kJ/∘C,
what is the heat of combustion per gram of the material?
A researcher studying the nutritional value of a new candy places a 5.50g sample of the candy inside a bomb calorimeter ?
