A patient receives 2700mL of an IV solution containing 4g g of glucose per 100 mL .How much energy, in kilojoules, does the patient obtain from glucose, a carbohydrate?
please help I keep getting the wrong answer
To calculate the energy obtained from glucose, we need to use the conversion factor that states 1 gram of glucose provides 17 kilojoules (kJ) of energy.
First, we need to determine the amount of glucose in the 2700 mL of IV solution.
Given that the solution contains 4 grams of glucose per 100 mL, we can set up the following proportion:
4 g glucose / 100 mL = X g glucose / 2700 mL
To solve for X, we can cross-multiply and then divide:
(X g glucose) = (4 g glucose * 2700 mL) / 100 mL
Now, we can calculate the amount of glucose in the IV solution:
(X g glucose) = (4 g glucose * 2700 mL) / 100 mL
Simplifying this calculation yields:
(X g glucose) = 108,000 g glucose / 100 mL
(X g glucose) ≈ 1080 g glucose
Now, we can calculate the energy obtained from glucose by using the conversion factor:
Energy = (mass of glucose) * (conversion factor)
Energy = 1080 g glucose * 17 kJ/g
Finally, we calculate the energy obtained from glucose:
Energy ≈ 18,360 kJ
Therefore, the patient obtains approximately 18,360 kilojoules (kJ) of energy from the glucose in the IV solution.
I did this for you last night before I went to bed; what's the problem?
When you keep getting the wrong answer the BEST thing you can do is to show your work. That way we aren't fumbling in the dark.
