Asked by Alex
The following substances undergo complete combustion in a bomb calorimeter. The calorimeter assembly has a heat capacity of 5.136 ^ C. In each case, what is the final temperature if the initial water temperature is 22.37^ C? 0.3268g caffeine, C8H10N4 (heat of combustion = -1014.2 kcal/mol caffeine)

1014.2 kcal/mol x (0.3268 g/molar mass caffeine) = kcal. Change to cal = ?q
?q = Ccal x (Tfinal-Tinitial).
Solve for Tfinal.
By the way, you omitted the unit for Ccal. That's 5.31 WHAT/degree C. If that is kcal change to cal.
?q = Ccal x (Tfinal-Tinitial).
Solve for Tfinal.
