How much Dextrose is in 500 mL of 20% Dextrose?

To determine how much Dextrose is in a 500 mL solution of 20% Dextrose, it’s important to understand the percentage concentration. A 20% solution means that there are 20 grams of Dextrose in every 100 mL of solution.

To find the total amount of Dextrose in 500 mL, you can set up a proportion based on the concentration:

1. Calculate how many grams of Dextrose are in the entire 500 mL.

• Since 100 mL contains 20 grams of Dextrose, 500 mL will contain:

[

\text{Amount of Dextrose} = \left( \frac{20 \text{ g}}{100 \text{ mL}} \right) \times 500 \text{ mL}

]

• This simplifies to:

[

\frac{20 \times 500}{100} = 100 \text{ g}

]

This calculation shows that in 500 mL of a 20% Dextrose solution, there are indeed 100 grams of Dextrose. Understanding this concept is essential for accurate dosing and compounding in pharmacy
