In an experiment, a 0.5297 g sample of diphenylacetylene (C14H10) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.369 x 10^3 g of water. During the combustion the temperature increases from 22.95 to 26.05°C. The heat capacity of water is 4.184 J g-1°C-1. The heat capacity of the calorimeter was determined to be 916.9 J/°C.
1. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of diphenylacetylene based on these data.
