Problem: A 1.800-g sample of solid phenol (C6H5OH(s)) was burned in a bomb calorimeter, which has a total heat capacity of 11.66 kJ/oC. The temperature of the calorimeter plus its contents increased from 21.36oC to 26.37oC.You may want to reference (Pages 178 - 183)Section 5.5 while completing this problem.What is the heat of combustion per mole of phenol?

FREE Expert Solution

We are asked to calculate the heat of combustion per mole of phenol.


Calculate heat:

Q = CcalTQ = (11.66 kJ°C)(26.37°C -21.36°C )Q = (11.66 kJ°C )(5.01°C )

Q = 58.42 kJ
