What is the heat of combustion per gram of phenol?

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/∘C. The temperature of the calorimeter plus its contents increased from 21.36∘C to 26.37∘C.1)What is the heat of combustion per gram of phenol?2)What is the enthalpy per mole of phenol?

(11.66 kJ/∘C) x (26.37∘C - 21.36∘C) = 58.4166 kJ produced1) (58.4166 kJ) / (1.800 g) = 32.45 kJ/g2)(58.4166 kJ) / (1.800 g) x (94.11124 g phenol/mol) = −3054 kJ/mol phenol[The minus sign did not come from the calculations. It is the convention for exothermic processes.]... Show More
