Final answer:
Each gram of dextrose in a solution provides approximately 17 kilojoules (kJ) of energy.
Step-by-step explanation:
The average fuel value of carbohydrates is 17 kJ/g. However, the question specifically asks about dextrose, which is a type of carbohydrate known as D-glucose, with the formula C6H12O6. Dextrose has a similar fuel value, so it can be assumed that each gram of dextrose in a solution would also provide approximately 17 kilojoules (kJ) of energy.
