Phthalates used as plasticizers in rubber and plastic products are believed to act as hormone mimics in human. The value of deltaHcombustion for dimethylphthalate (C10H10O4) is 4685 kJ/mol. Assume 1.035 g of dimethylphthalate is combusted in a calorimeter whose heat capacity (C calorimeter) is 7.293 kJ/Celsius at 20.142 Celsius. What is the final temperature of the calorimeter?

To find the final temperature of the calorimeter after the combustion of dimethylphthalate, we can use the principle of conservation of energy. The heat released during the combustion of the dimethylphthalate is transferred to the calorimeter and its surroundings, resulting in a change in temperature.

Here's how we can calculate the final temperature:

1. Calculate the heat released during the combustion of dimethylphthalate:
Mass of dimethylphthalate (m) = 1.035 g
Molar mass of dimethylphthalate (M) = 222.22 g/mol
ΔH_combustion = 4685 kJ/mol

Heat released (q) = ΔH_combustion * (m / M)

2. Calculate the heat absorbed by the calorimeter and surroundings:
Heat absorbed (q) = -q (according to the principle of conservation of energy)

3. Calculate the change in temperature (ΔT) of the calorimeter and surroundings using the heat capacity of the calorimeter:
C_calorimeter = 7.293 kJ/°C
ΔT = q / C_calorimeter

4. Calculate the final temperature:
Final Temperature = Initial Temperature + ΔT

Note: The initial temperature is not provided in the question, so you will need to know that to get the final temperature.

By following these steps, you can calculate the final temperature of the calorimeter after the combustion of dimethylphthalate.
