∆Hf values are used to find products-reactants. 4(-393.5)+6(-285.8)=-3288.8, sum of products, minus 2(-84)= -3120.8
divide by 2 since its two moles and you only want one= -1560.4
divide by the molar mass of ethane, 30.07, and you get -51.892.
make it positive because fuel values are positive and you get 51.892 as your final answer

How do you convert sugar grams to kilojoules?
To convert sugar grams to kilojoules, you can use the conversion factor that 1 gram of sugar is equal to approximately 17 kilojoules. Multiply the number of sugar grams by 17 to get the equivalent amount in kilojoules. This conversion is based on the average energy content of sugar.
How much more energy is released from burning 1g of natural gas compared to burning 1g of wood?
Burning 1 gram of natural gas typically releases about 13.6 kilojoules of energy, while burning 1 gram of wood releases approximately 15.5 kilojoules. This means that, contrary to the initial assumption, wood actually releases more energy per gram than natural gas. Therefore, natural gas releases about 2 kilojoules less energy per gram compared to wood.
Ranking of fuel values of fats proteins carbohydrates?
Fats provide the highest fuel value at 9 calories per gram, followed by carbohydrates at 4 calories per gram, and proteins at 4 calories per gram.
How do I convert the enthalpy of vaporization of water in joules per gram from kiloJoules per mole?
Lets say, for example the enthalpy is equal to 1200 joules/gram. You take 1200 joules/gram * (# of grams)/one mole [now you can cancel grams and it is now joules/mole.] Then convert the answer to kilojoules by dividing by 1000.
What does kJ g-1 mean?
The term kJ g⁻¹ stands for kilojoules per gram, which is a unit of measurement used to express energy content or energy density in a material or substance. It indicates the amount of energy (in kilojoules) contained in one gram of that substance. This measurement is commonly used in nutrition to describe the energy provided by food items. Higher kJ g⁻¹ values indicate a greater energy content per gram.
What do you mean by calorific value?
