How many milliliters of a 50% dextrose solution are needed to obtain 35g of dextrose?

To determine how many milliliters of a 50% dextrose solution are needed to obtain 35 g of dextrose, it is crucial to understand what a 50% solution means. A 50% dextrose solution contains 50 grams of dextrose per 100 milliliters of solution.

To find out how much solution is needed for 35 grams of dextrose, we can set up a proportion based on the concentration of the solution:

If 50 grams of dextrose is found in 100 milliliters of the solution, then the amount in 1 milliliter can be calculated as follows:

1. Calculate the amount of dextrose per milliliter:

[

\frac{50 \text{ grams}}{100 \text{ mL}} = 0.5 \text{ grams/mL}

]

2. Now, to find out how many milliliters will give you 35 grams of dextrose, use the relationship:

[

\text{mL needed} = \frac{\text{grams of dextrose}}{\text{grams/mL}} = \frac{35 \
