24. Phthalates, used to make plastics flexible, are among the most abundant industrial contaminants in
the environment. Several have been shown to act as hormone mimics in humans by activating the
receptors for estrogen, a female sex hormone. In characterizing the compounds completely, the value of
AH comb for dimethyl phthalate (C10H1004) was determined to be -4685 kJ/mol. If 1.00 g of dimethyl
phthalate is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 7.854 kJ/°C and at an initial
temperature of 20.215 °C. What would be the expected final temperature of the calorimeter?
