Methanol is the fuel in "canned heat" containers (e.g., Sterno) that are used to heat food at cocktail parties. The combustion of methanol follows the thermochemical equation: 2CH3OH(1) + 302(g) → 2CO2(g) + 4H2O(1) AH° = -1199 kJ How many kilojoules are liberated by the combustion of 49.2 g of methanol?
