Acetic acid, HC2H3O2\mathrm{HC}_2 \mathrm{H}_3 \mathrm{O}_2, is responsible for the sour taste of vinegar. Combustion of acetic acid gives off 14.52 kJ/g14.52 \mathrm{~kJ} / \mathrm{g} of heat. When 15.00 g15.00 \mathrm{~g} of acetic acid is burned in a bomb calorimeter (heat capacity =2.166 kJ/C=2.166 \mathrm{~kJ} /{ }^{\circ} \mathrm{C} ) containing 0.800 kg0.800 \mathrm{~kg} of water, the final temperature in the calorimeter is 64.14C64.14^{\circ} \mathrm{C}. What was the initial temperature of the calorimeter?

14.52 kJ/g of heat is released when acetic acid undergoes combustion. Meanwhile, burning 15.00 g of acetic acid (heat capacity = 2.166 kJ/°\degreeC) causes the final temperature of the calorimeter and the 0.800 kg of water in a bomb calorimeter to be 64.14°\degreeC.

The goal of this exercise is to determine the initial temperature of the calorimeter.
