Question
When one mole of C6H6 is burned, 5.69 MJ of heat is produced. When the heat from burning 9.69 g of C6H6 is added to 5.69 kg of water at 21.0°C, what is the final temperature of the water?

heat produced by burning 9.69g C6H6 is
5.69 mJ/mol x (9.69/molar mass C6H6) = ? MJ. Convert to J. Then
J = mass H2O in g x specific heat H2O x (Tfinal-Tintial) and solve for Tf.
