A student heated 75.0 mL of water in an aluminum container using an alcohol burner filled with methanol (CH3OH). The mass of the aluminum container was 44.5 g. The initial temperature of the water was 16.5 degrees C and the final temperature was 23.0 degrees c. The initial mass of the alcohol burner was 113.54 g and the final mass as 112.97 g. Calculate the molar heat of the combustion of methane. The specific head capacities are Cal=0.900 j/g degrees c and Ch2o=4.18 j/g degrees C.
