You have a 5% dextrose solution. How many ml will give you 25g of dextrose?

To determine how many milliliters of a 5% dextrose solution are needed to obtain 25 grams of dextrose, the concentration of the solution can be utilized. A 5% solution means that there are 5 grams of dextrose in every 100 milliliters of solution.

First, to find out how many grams are in 1 milliliter, you can set up the following relationship:

5 grams of dextrose / 100 milliliters of solution = 0.05 grams of dextrose per milliliter.

Next, if you want to find out how many milliliters are needed to obtain 25 grams, you can use a straightforward equation. Since you know that each milliliter contains 0.05 grams of dextrose, you need to determine how many milliliters will give you 25 grams:

Milliliters needed = Total grams desired / Grams per milliliter

Milliliters needed = 25 grams / 0.05 grams per milliliter = 500 milliliters.

Therefore, the correct answer is 500 milliliters, which corresponds to the amount required to provide 25 grams of dextrose in a
