Take a look at the thermochemical equation for the combustion of hexene gas shown below. If the reaction is conducted in a calorimeter containing 445 mL of water at 19 degrees celsius (initially) and a total of 7.4 grams of hexene (C6H12) is combusted, what will the final temperature of the water be? Assume the density of water is 1 g/mL and the specific heat capacity of water is 4.18 J/gC. Round your answer to 2 decimal places, if necessary. Do not include units in your final answer.
C6H12(g) + 9O2(g) --> 6H2O(g) + 6CO2(g)
Hcombustion = -432.09kJ/mol
