To determine the experimental heat of combustion of an alcohol, the set-up was assembled as shown below. Experimental results and standard constants were tabulated: Thermometer Draught shield Experimental Data: Initial mass of spirit burner with alcohol 224.59 grams 223.42 grams 26.3°C Copper calorimeter Final mass of spirit burner with alcohol Initial temperature of water in calorimeter before heating Final temperature of water in calorimeter after heating Clamp 56.5 °C Water Standard Constants: (250 ml) 4.184 Joule/gram°C Specific heat of water Molar mass of the alcohol used 46 gram per mole -1368 kJoule per mole Spirit burner Theoretical heat of combustion of the alcohol Liquid fuel Express how close or how far the experimental value for the heat of combustion is to the theoretical expected value.
