Phthalates used as plasticizers in rubber and plastic products are believed to act as hormone mimics in humans. The value of ΔHcomb for dimethylphthalate (C10H10O4) is –4685 kJ/mol. Assume 1.01 g of dimethylphthalate is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 6.05 kJ/°C at 20.5 °C. What is the final temperature of the calorimeter?
