Answer to Question #75574 in General Chemistry for Shae

Question

A patient receives 2500 ml of an IV solution containing 5g of glucose per 100 ml. How much energy in kilojoules, does the patient obtain from glucose, a carbohydrate ?

Answer 1

The total mass of glucose is:
m(glucose)=(2500 mL×5 g)/(100 mL)=125 g
One gram of glucose can give 16 kJ energy.
The total energy that patient obtain from glucose is:
E=125g×16 kJ/g=2000 kJ
Answer:
2000 kJ the patient obtain from glucose.
