Final answer:
The mass flow of glucose into the body from an intravenous infusion of 25 grams of glucose per liter at a flow rate of 4 milliliters per minute is 0.1 grams per minute, which is none of the provided answer choices.
Step-by-step explanation:
The question concerns calculating the mass flow rate of glucose into the body from an intravenous infusion.
To find the mass flow rate, we first calculate the mass of glucose that is delivered per minute. Since the concentration is given as 25 grams of glucose per liter, and the flow rate is 4 milliliters per minute, we can set up a proportion to find the mass of glucose infused per minute.
The conversion is as follows:
- 1000 milliliters = 1 liter.
- 25 grams of glucose are in 1000 milliliters of the solution.
- We need to find out how many grams are in 4 milliliters.
Using proportion, the calculation is 25 grams/liter * (4 milliliters / 1000 milliliters/liter), which simplifies to 0.1 grams/minute.
Therefore, the mass flow of glucose into the body is 0.1 grams per minute, which is not one of the provided options (A) 1 gram/minute, (B) 4 grams/minute, (C) 16 grams/minute, (D) 100 grams/minute.
