Unformatted text preview: A 1.640 g sample of benzoic acid is combusted in a bomb calorimeter. The temperature of the calorimeter increases from 22.25º C to 27.20 ºC. What is the heat capacity of the calorimeter?-q sys = q surr-q benzoic acid = q Cal-q benzoic acid = C Cal ∆ T Note q must be in kJ or J. It cannot be in kJ/g.-(-26.38 kJ/g)(1.640 g) = C Cal (27.20 – 22.25) 8.74 kJ/ o C = C Cal...
