A 2.56 g sample of anthracene C14H10, was burned to heat an aluminum calorimeter (mass=948g). Explain the calorimeter contained 1.50 L of water with an initial temperature of 20.5 C as well as a final temperature of 34.3'C
a) Compute the molar heat of combustion of anthracene.
b) Suppose the actual value for ?H= -7150 kJ/ mol, what is the percentage error?
