The sign of the heat of formation matters. Using hess's law: 2(-238kJ) + 4(242kJ) + 2(393)= -1279=Heat of reaction Heat of combustion of methanol is just the heat of reaction divided by the molar coefficient for methanol in the chemical equation so about -639.5kJ/mol. In acuality it is somewhere near -727kJ/mol.
Example #4: A 29.5 g sample of methanol at 208.9 K is mixed with 54.3 g of methanol at 302.3 K. Calculate the final temperature of the mixture assuming no heat is lost to the containers and surroundings. The specific heat of methanol is 2.53 J gÂ¯ 1 KÂ¯ 1.Solution:xample #1: Determine the final temperature when 32.2 g of water at 14.9 Â°C mixes with 32.2 grams of water at 46.8 Â°C. This is problem 8a from Worksheet #2. First some discussion, then the solution. Forgive me if the points seem obvious:
