Question

Into a steel chamber of a calorimeter is placed 3.2 g of methanol, CH3OH. The chamber is then filled with oxygen at a pressure of 10 atm. After the outer chamber is filled with water (3000 g at 25 degree celsius), the alcohol-oxygen mixture is ignited. Shortly thereafter, the combustion is complete. The final temperature of the water is measured as 30.2 degree celsius. The steel combustion chamber weighs 2100 g and has a specific heat of 0.46 J/g-K. Calculate the heat taken up by the combustion chamber and the water in which it is immersed.

Answer 1

Calculate also the heat liberated in kilojoules for the combustion of 1 mole of methanol.
