A 3.51 g sample of benzene, C 6 H 6, was burned in a bomb calorimeter in an excess of oxygen. The initial temperature was o C and rose to o C. The heat capacity of the calorimeter and contents was kJ/ o C. Find q (heat given off) for the combustion of 1 mol of benzene.
A 3.51 g sample of benzene, C 6 H 6, was burned in a bomb calorimeter in an excess of oxygen. The initial temperature was o C and rose to o C. the heat capacity of the calorimeter and contents was kJ/ o C. Find q for the combustion of 1 mol of benzene. C 6 H 6 (l) + 15/2 O 2 (g) 6CO 2 (g) + 3H 2 O(l) 3.51 g T = o C What units do we desire?

If we could find the number of kJ and the number of moles of benzene, we could divide the kJ by the moles to get our answer!
A 3.51 g sample of benzene, C 6 H 6, was burned in a bomb calorimeter in an excess of oxygen. The initial temperature was o C and rose to o C. the heat capacity of the calorimeter and contents was kJ/ o C. Find q for 1 mol of benzene. C 6 H 6 (l) + 15/2 O 2 (g) 6CO 2 (g) + 3H 2 O(l) 3.51 g T = o C = kJ o C = mol BZ 3.51 g
Find q for 1 mol of benzene. C 6 H 6 (l) + 15/2 O 2 (g) 6CO 2 (g) + 3H 2 O(l) 3.51 g T = o C = kJ o C = mol BZ 3.51 g And now?
Find q for 1 mol of benzene. C 6 H 6 (l) + 15/2 O 2 (g) 6CO 2 (g) + 3H 2 O(l) 3.51 g T = o C = kJ o C = mol BZ 3.51 g kJ mol Bz 3264
