Salicylic acid, C7H6O3,?

Question

Salicylic acid, C7H6O3, has been suggested as a calorimetric standard. Its heat of combustion is -3.023 103 kJ/mol C7H6O3. From the following data determine the heat capacity of a bomb calorimeter assembly (that is, the bomb, water, stirrer, thermometer, wires, and so forth).


mass of salicylic acid burned: 1.111 g
initial calorimeter temperature: 23.07°C
final calorimeter temperature: 29.55°C

Answer 1

molar mass of Salicylic acid: 138.123 g/mol.
The answer is:
(3.023kJ/mol)*(1.111 g)/{(138.123 g/mol)*(29.55°C-23.07°C)}
= 3.752 J/gK

Answer 2

C7h6o3
