When 4.65 g of sinapinic acid, C11H12O5 is burned in a bomb calorimeter containing 7.07 kg of water originally at 27.91°C, 82.536 kJ of heat is evolved. The calorimeter constant is 4085 J/°C. Calculate the final temperature in Kelvin.

q = m*c*dT
q = 82,536 J
m = 7070 g H2O
C = 4.184 J/g*C for water
dT = Tfinal - Tintial.
Substitute and solve for Tfinal in celsius. Then convert to kelvin. Post your work if you get stuck.
