Homework Answers
Mass of the compound = 1.479 gm
Molar mass of the compound = 142.16 g/mol
Moles of the compound = 1.479 gm / 142.16 g/mol = 0.01040377 Moles
Amount of the heat released by 1.479 gm = 0.01040377 Moles x 3791 KJ / Mol = 39.44 KJ
Temperature of the calorimeter raised = 6.637 0C
Heat capacity of the calorimeter = 39.44 KJ / 6.637 0C = 5.942 kJ / 0C
Hence the heat capacity of calorimeter is 5.942 kJ / 0C
