A total of 11.4 grams of a certain fuel (Mr = 114 g mol^-1) is completely burned. The heat generated can raise the temperature of 100 mL of water by 5 C. If the density of water is 1 g mL^-1 and the specific heat of water is 4.2 J g^-1 C^-1, the heat of combustion of the fuel is ...
with temperature, such that pure water will have a density of 1 at 4°C, but water heated to the boiling point will have a density of 0.959 at 100°C. This
