Bomb Calorimeter, gross heat of combustionIn the following experiment 1.1651g of benzoic acid (6318 cal/gm) produced a net corrected temperature rise of 3.047C, also 8 cm (2.3 cal/cm) of fuse wire were consumed in the firing. How does one go about to compute the gross heat of combustion, in cal/gram. Then using this standardization how does one find the gross heat of combustion of this following unknown, in which 1.354g and 7 cm of fuse wire, with a temperature rise of 2.987C were consumed in the firing.
